Arroz con gambas y calamar

1. step 1
2. Peel and devein most of the prawns (a fishmonger should be able to do this for you), keeping a few whole for decoration, if you like. Heat the olive oil in a large frying pan or shallow flameproof casserole over a medium-low heat and fry the onion for 5 mins until softened. Add the bay leaf, saffron, rice and tomato purée, and cook for 1-2 mins more, stirring.

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.
