4. To make the sauce, put all the ingredients into a blender with 1 tbsp water and whizz until as smooth as possible. This will make more than you’ll need for the recipe but will keep for a week in an airtight jar.

6. Heat a griddle or frying pan to high. Brush away the garlic and parsley stalks from the steaks and season well. Sear the steaks for 2 minutes on each side then rest on a plate. Put the ciabatta halves onto the plate, toasted-side down, to soak up any juices.

Cooking notes

When scaling protein-led dishes, weigh the meat rather than counting pieces, and remember that the pan size limits how much you can sear at once.

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.
