"Toad in the hole" is a classic British dish for the colder months. To make it veggie you can use veggie sausages, sure. But this version, with the rich flavours of butternut squash and sage, is great! It's a good Sunday roast when you put it with roast potatoes, gravy and more.

Oven dish with a freshly-baked squash-in-the-hole: like a Yorkshire pudding stuffed with luscious orange squash and green sage leaves

Butternut squash is a good choice. I also made one using a "blue pumpkin" which appeared in our local grocer's, which works fine too. In either case, if the skin is not too thick then I recommend leaving the skin on -- it gives a good bit of texture to the dish. You do need to remove any knobbly or rough bits of skin though.

Serves 2--3. Takes maybe 90 minutes, including a lot of oven-time where you can do other things.

For two people I use a roasting tin about 20cm x 20cm. A larger tin is OK too - the dish can be wide and flat in that case, lots of surface area.

First we cook the squash until it's close-to-ready. You can do this just-in-time but it's a bit complex to juggle everything in the oven, so I suggest doing it first, as follows:

Heat the oven to 180C. You don't need to peel the squash but take off any knobbly bits, then slice in two and scoop out the seeds. Chop the squash into "chunky chip" shapes: i.e. cuboid finger-sized pieces e.g. 2cm x 2cm and not longer than about 5cm.

Put some oil in a metal baking tray, add the squash pieces and toss them to coat. Cook them in the oven for 20 minutes until they're starting to acquire some brown roasty colour -- but not too much! -- they'll be cooked more later. Take the tray out and put it to one side. It doesn't matter whether the squash has time to cool down or not.

Mix the batter: mix the eggs, milk, flour and mustard in a bowl, whisking with a whisk to beat out any small lumps. Let this rest for 15 to 30 minutes.

When you're ready for the main cook, turn the oven up to 200C. Preheat the dish that you'll be cooking in - put about 2 tbsp of vegetable oil in it and put it in the oven to heat right up. This may take 5 minutes. Stir the batter again.

Prepare the sage leaves: the small ones kept whole and the large ones chopped to a similar size.

Prepare your work surface ready for quickly assembling the dish: you'll need somewhere to stand the hot tin, and you'll need the batter, the squash and the sage. Working quickly, take the tin out (careful, hot oil), pour the batter in, arrange the squash pieces evenly (they should stick out a bit), then finally place the sage pieces into the batter in good spots between the squash pieces.

Then put the dish back in the oven and cook for 25--30 minutes until the batter is crispy at the sides and nicely cooked and starting to brown on top.

To serve, ideally you can cut slices of it and gently lift them out onto plates. To make that work, you should run a knife around the edge first to free it from the baking dish.

Two black teas grown in France!

Two slim brown packets, with the aforementioned names on them. They're standing on my countertop next to my mug which is poised and ready to go

There are growing numbers of small tea farms appearing in Europe. There's some pre-history to this, but most of what I'm referring to is independent little initiatives trying it for the first time. I've written about Dutch-grown black tea earlier this year. And at Brussels Tea Festival I met people from two French farms, one in Brittany and one in Basque.

Here are my tasting notes. I only bought their black tea, since it's my main interest, but they're making others too. They are small producers - you buy very small batches of tea. It's high-quality, often intended for multiple infusions. Not cheap, of course. I drink it without milk or anything else, and that's probably the intention too. The general advice is to brew these for 3 or 4 minutes at 90 degrees, but you can try different ways to see what suits you best.

I'm going to say straightaway that I have a favourite out of these two, and it's the "Mendiko" from Basque country. I had the same impression when I tasted them at the tea festival, but I was super keen to try them both out at home:

Mendiko-Tea - tea grown in the Basque country

Nice-looking thin dark leaves. Strangely, they specify on the packet that it should be brewed for 3 minutes and 34 seconds! Are they having a laugh?? Anyway I did as I was told, with 90 degree water and 3g of tea in my mug. The resulting brew is light-coloured red, but really what strikes me at first is a gorgeous honeyed smell with a hint of biscuit - really appealing.

Drinking it, the honeyed flavour continues through, nice, with a medium body behind it. I didn't expect it to be very "hefty" like a strong black tea for a Brit, and indeed it's light, but it does fill the mouth. It's a great cuppa.

Second brew: the aroma is more muted, of course, but the flavour is still very present.

Third brew: doesn't taste of much. Fourth brew: the main flavour has gone, and what remains is pure watery with a slight lingering sweetness. You could well stop after two, but this tea exits gracefully!

Kerizel - tea grown in Brittany

Nice-looking thin black long leaves - very long and wiry. I brewed it for 4 minutes.

The tea has a nice solid red colour, and a lovely sweet golden smell. The taste is also nice and golden, on the front of the mouth. I miss a little the "heft" of anything dark or at the back of my mouth. I find this tea a bit more onedimensional than the Mendiko or the Zuyderblad - for me it's not as moreish.

The second infusion is viable, it's the same but a bit less pronounced - slightly more balanced, even! - but I don't get much from any further brews. Still, no astringency or anything like that on the exit, which is fine.

Glad I bought these packets. It's pretty rare to find tea grown so close to home, and I'm looking forward to seeing what else is out there.

I tasted this amazing vegan version of a Moroccan dish in Tangier (at the NBTA restaurant), and wow - such delicate flavours! I definitely had to make a note and then try to recreate it. I think I've done pretty well!

The finished dish should be a gloopy honeyed collection of lovely stewed objects, garnished with almonds and sesame seeds, and if you're feeling glam even some rose petals or orange blossom?

Mrouzia is traditionally made with lamb so you can choose whatever non-flavoured fake meat you like, ideally something a bit stew-friendly. I use some nice seitan pieces that come in a jar.

The spice mix is "ras-el-hanout" which basically indicates the classic Moroccan spice mix. There shouldn't be any chilli in it - that's not appropriate for this dish. We've had a couple of different ras-el-hanouts and some of them had chilli in.

Serves 2 people, takes 30 minutes.

Bloom the saffron by adding it to half-a-cupful of hot water, five minutes before you use it.

In your stewing pan, add a splash of water and the butter. Turn the heat on so that the butter begins to melt while you also add the garlic, cinnamon stick, salt, pepper, ras-el-hanout, and the bloomed saffron with its water. Give it a simple stir to mix.

Add the fake meat, apricots and prunes. Bring it all up to a medium-hot heat and let it stew gently for ~30 minutes, with a lid on, until it's nicely reduced and there's not that much liquid left. Stir occasionally.

- Note: if you want to make this dish ahead of time, you can pause the recipe at this point e.g. take it off the heat. -

While the stew is cooking, prepare the almonds. If they aren't already halved, slice them lengthways. Then roast for 5-10 minutes in an oven at 180C (or a frying pan on a medium-to-low heat), and take them out again. Save a few of the almonds to garnish at the end, but add most of the roasted almonds to the pan, when there's maybe five or ten minutes cooking time left.

When the stewing time is done, and the stew quite well reduced, remove the cinnamon stick then add the honey and the sesame oil and stir. Let it warm/cook for a minute more. Check for seasoning (any lemon needed?).

Serve garnished with a generous sprinkle of sesame seeds over the top, as well as the reserved almonds.

Accompany it with bread or couscous.

Tea grown in the Netherlands! It's real! Earlier this month we visited Het Zuyderblad near Eindhoven. The tour was very informative (NB it was in Dutch). We encountered live tea plants for the first time, I think, and there was a nice cosy tasting session in their elegant converted barn space.

And here's the tea itself. In this case a black tea (I think they also produce a green): very high quality black tea, reminding me a little of Yunnan Hong cha (the golden taste is there, muted but confident).

Here are my home tasting notes:

I followed the instructions: a mug with 2 grams of tea, 100 C, 3 minutes. The tea has a good rich brown colour. The scent is a really clear "Maltesers" smell---which as Brits know means malty, sweet and chocolatey. The taste follows through on that: a lot like a "Yunnan gold" it's bright and malty, sweet, with just a touch of cocoa, while also rounded and medium-bodied. I like it - a satisfying single-origin black tea."

Second brew: 100 C, 8 minutes. malty but in a more gentle biscuity way. Good, though a touch thin for my taste, even though I gave it 8 minutes. It's fine to make a second brew from it but I might tweak the settings next time.

Third brew: I only did this as an experiment. Of course it's very thin, too thin for a normal drink, but what's noticeable is there's no astringent flavour at all (which I would usually get from over-brewing a black).

Availability: it's NOT EASY to get hold of this tea. I don't think they currently produce enough to sell it regularly. You might need to go to one of their tea tours.

Morocco has a nice set of birds - fun to encounter, for a European. Easy to get to know them even in the cities. Here's my hit list:

  1. Moussier's redstart - This comes top of the list because
    (a) it's the national bird of Morocco!
    (b) it's endemic to the Atlas mountains - you only find it there!
    (c) we saw it foraging around while we stopped at the top of a mountain pass for a glass of mint tea! (The mint tea was for us. I don't know what the bird had.)
    (d) I took a classic photo of it. Can you see the Moussier's redstart? With its black-white-black-white upper pattern, and underneath its rust-red belly?

    Frankly, you see a semi-arid hilltop. Somewhere in there is a handful of pixels, smartly black-white-black-white and red like Moussier's redstart.

  2. Spotless starling. This looks similar to our familiar starling but is pure black instead of iridescent. It sings differently. And it waggles its wings in an endearing way while it sings. ... You have to see it in action.

  3. Alpine swift. These high-speed birds I've seen elsewhere, but the novelty is that there are many of them racing around in the city squares of Morocco, nesting in holes in the wall and then racing around flying low and screaming enthusiastically as they race past you in groups diving for insects.

  4. House bunting. This little bird is noticeable for its all-grey head and its all-brown body, which really is a different colour-scheme than most birds you'll see around. It's common in north-west Africa and so I guess Morocco is a good plac to see them. We often saw them living/foraging actually inside riads, and elsewhere.

  5. Common bulbul. The bulbul I've not seen before, but it's apparently common all across Africa. It was common in cities, with a pale brown topside and a white underside.

  6. White stork. The stork is pretty common where I come from but in southern Spain and northern Morocco there were many. What's especially noticeable about storks is their massive nests, which they build right at the top of mobile phone masts or disused mosque minarets, making intriguing architectural intervensions.

Morocco's street food gave me a lot to discover! Whether from a stall, or from someone pushing a hand-cart through the busy medina (market), I was surprised how many tasty things were commonplace there, and new to me. Here are some of my favourites:

A street-food seller at his cart, scooping chickpeas into a sandwich

And the sweet snacks:

Also juices! So many fruit juices! Many stands were simply operated by one person with a pile of fruit and a manual squeezer, which is a good thing to look for since you can guarantee the juice is freshly-squeezed and unadulterated. Some great combos that we had are peach and lemon, avocado and date (with some milk in this one, we think), and sugarcane with lemon. Simply sugarcane, crushed with a bit of added lemon, is surprisingly delicious!

I almost forgot to mention one of my favourite juices: pure pomegranate juice -- multiple times there was a stall which was simply a man with a pile of pomegranates, and a juicer. (OK, also a little tea strainer and some plastic cups.) Pomegranates are expensive, where I come from, because they don't grow where we are - so it's impressive that for an OK price he'll squeeze 3 pomegranates straight into a cup for you. The sweet-sour pomegranate juice is so great on a hot day.

And I want to mention a couple of things that aren't street food, but

This Kurdish lentil soup is lovely and smooth. Simple but nicely balanced. A handful of rice balances the lentil flavour nicely and the whole thing becomes very smooth (even without blending it).

Thanks to the Asylum seekers' and Refugees Support Group, Nelson, UK, for writing this down, and thanks to the Kurdish woman whose name I don't know, for passing this recipe on!

Makes 6--8 servings, takes 45 minutes.

Wash the lentils in warm water, then rinse them in cold. Put in a pan with ~4cm of cold water over them, cover, bring to boil.

Once the lentils boil turn the heat down, skim off the scummy bits - no need to be precise, doesn't matter if some remains. Do this while in parallel you start the next step of cooking the onions. (Maybe this means cooking the lentils for 10-15 minutes or so?)

Chop the onions finely and fry in a frying pan with the oil, on a medium heat, until starting to brown.

Tip the onions and oil into the lentil pan, plus 1 mug cold water or more (a pint?). Add salt, chilli, turmeric, rice.

Gently simmer for about 30 to 45 minutes - so that it is the right soupy consistency you want! If you need to add more water as it gently summers, do so.

Oven-roasted fennel is great - it's roasty, and yet still fresh and fragrant. This simple dish makes the most of it. We made this in 2019 and remembered it today! And it's as lovely as it is easy.

Serves 2. Takes 35 minutes.

Preheat an oven at 180C, and lightly oil a baking tray.

Chop the fennel in half top to bottom, then cut into slices approx half a centimetre thick. (Those cuts are also top to bottom, so that you're left with connected half-moon pieces.) Save any wispy "fennel tops" to one side, to use as garnish at the end.

Crush or finely chop the garlic. Zest and juice the lemon. Put half of the lemon juice into a mixing bowl, and add 1 tbsp oil plus the garlic and a good pinch of salt. Whisk this with a fork, then add the fennel pieces and give everything a good but gentle mix, to get them evenly coated.

Spread the fennel pieces out on the baking tray, then roast in the oven for 30 minutes. Half-way through, turn the pieces over.

Meanwhile, wash and finely chop the parsley.

Five minutes before the fennel is ready, in a large pan of boiling water, cook the tagliatelle according to the pack instructions. Once you've drained the pasta, return it to the pan, and add a dash of olive oil plus the oat cream, salt and pepper. With two forks, toss this around so that all the pasta is separated and nicely coated. Check the seasoning. Then add the parsley and mix again.

Take the fennel out of the oven and add it to the pasta. Sprinkle over the lemon zest and the remaining lemon juice, and gently stir again to mix.

Serve in 2 dishes, with the fennel tops chopped and sprinkled over.
