Kumpir

1. If you order kumpir in Turkey, the standard filling is first, lots of butter mashed into the potato, followed by cheese. There’s then a row of other toppings that you can just point at to your heart’s content – sweetcorn, olives, salami, coleslaw, Russian salad, allsorts – and you walk away with an over-stuffed potato because you got ever-excited by the choices on offer.
2. Grate (roughly – you can use as much as you like) 150g of cheese.
3. Finely chop one onion and one sweet red pepper.
4. Put these ingredients into a large bowl with a good sprinkling of salt and pepper, chilli flakes (optional).

Cooking notes

Scaling works best when you weigh ingredients rather than measure by volume — small differences in packing can compound at higher multipliers.

For volume-to-weight conversions of any ingredient — flour, sugar, butter, salts — use the ingredient converter. To translate the recipe's oven temperature between °C, °F and gas mark, see the temperature converter.

When you scale this recipe up or down, remember that cooking time does not scale linearly. A doubled cake takes longer, but not twice as long; a doubled soup takes roughly twice as long. The cooking-time guide gives sensible starting estimates by dish geometry.
