Rumbledethumps
Borders bake of potato, cabbage and onion under cheddar
Rumbledethumps comes from the Scottish Borders, a thrifty supper of mashed potato, buttery cabbage and onion baked under a crust of cheddar, usually made with the Sunday roast leftovers on a Monday night. The name is said to come from the rumbling and thumping of the pans. Traditional cheddar is often made with animal rennet, so use a vegetarian cheddar if that matters to you. Chef's tip: cook the cabbage only until bright and just tender so it keeps some bite in the bake.

Caramelised clay-pot tofu and mushrooms
Kho is the slow braise of the Mekong Delta: food simmered in a little clay pot (nồi đất) with dark caramel and seasoning until the sauce is sticky and the flavours go deep. This vegetarian cousin of cá kho tộ (braised fish) uses golden tofu and meaty mushrooms in place of fish, cooked in coconut water, as cooks do in the south, and finished with plenty of black pepper. Serve it bubbling in its pot with steamed rice and a sour soup or plain boiled vegetables. Chef's tip: take the caramel (nước màu) to a deep mahogany, darker than you think, just before it smokes; pale caramel only tastes sweet, while dark caramel gives the bittersweet, smoky flavour of a real kho.

Black bean tacos with lime slaw
Proof that a meat-free taco night can be the best one. The beans are mashed with chipotle and cumin so they hold together in the tortilla, and a quick lime slaw adds crunch.
Mexican
Spinach with mushrooms
A bright green, savoury puree of potato, mushrooms and fresh spinach cooked in home-made baby stock. Thick and smooth, it's a good way to get iron-rich greens into babies of 8–18 months. Serve warm; spare portions freeze well.
