New York potato knishes
Baked pastry rolls stuffed with onion and mashed potato
AmericanKnishes came from Eastern Europe with Jewish immigrants and became Lower East Side street food, sold from carts and the old knishery on Houston Street with a dab of brown mustard. A thin, stretchy oil dough is wrapped around a peppery filling of mashed potato and deeply browned onions, then baked golden. Chef's tip: cook the onions slowly until truly brown and sweet; pale onions make a bland filling.

Method
0/6 doneStep 1: Mix the 10 ½ oz plain flour, 1 tsp baking powder and ½ tsp salt, then add the ¼ cup vegetable oil, 1 egg, ¼ cup warm water and 1 tsp white vinegar and knead 3 minutes to a soft, smooth dough. Wrap and rest for 1 hour at room temperature.
65 minStep 2: Boil the 2 lb floury potatoes in salted water for 18 minutes until very tender, drain and let them steam dry for 3 minutes, then mash.
22 minStep 3: Meanwhile fry the 2 onions in the 4 tbsp vegetable oil over a medium-low heat for 25 minutes, stirring now and then, until deep golden brown. Mix into the mash with the 1 ½ tsp salt and 1 tsp black pepper and cool.
25 minStep 4: Heat the oven to 375°F (350°F fan). Halve the dough and roll each half on a floured cloth into a very thin rectangle, about 25 × 40 cm.
10 minStep 5: Spoon half the filling in a 5 cm log along the long edge, roll it up loosely and trim the ends. Use the side of your hand to press the log into 6 pieces, twist them apart, and push the dough over each cut end to seal. Repeat with the rest.
15 minStep 6: Stand them sealed-side down on a lined tray, flatten slightly and brush with 1 egg. Bake for 30–35 minutes until deep golden. A common mistake is rolling the dough thick, which gives a bready knish.

Masala khakhra
Khakhra are thin chapaties roasted slowly on a griddle until they turn crisp, like a cracker. This masala version adds gram flour, fresh fenugreek, turmeric and chilli to the wheat dough. They are a light Gujarati breakfast or tea-time snack, and lovely with pickle, chutney or a smear of butter. You can also make them in a roti maker.
Indian
Okonomiyaki
Okonomiyaki (お好み焼き, 'grilled as you like it') is the pride of Osaka, where it's cooked on hot iron griddles in lively restaurants. Finely shredded cabbage is folded into a light batter with egg and spring onion, then fried into a thick, soft pancake with a crisp outside. It's painted with a fruity brown sauce and zigzagged with mayonnaise. Bonito flakes are usual on top; this vegetarian version uses seaweed flakes and pickled ginger instead. Chef's tip: don't press the pancake down with your spatula while it cooks. Osaka cooks leave it alone so the cabbage steams inside and stays light and fluffy; pressing squeezes out the air.

Coastal Mombasa mix
A Mombasa street-food bowl: chickpeas and potato simmered in coconut milk with raw mango and chilli, ladled into small bowls and topped with crisp lentil fritters, crunchy chevdo and red, green and tamarind chutneys. Make the fritters and chevdo ahead and assemble at the table. It's sweet, sour, hot and crunchy all at once.
