What each ingredient does

Kidneys
Provide the main savoury filling and meaty texture of the dish.
Butter
Cooks the kidneys gently and adds richness and a rounded flavour.

The step that matters

Cook the kidneys for 2-3 minutes. Kidneys turn tough and rubbery when overcooked, so a short, hot cook keeps them tender. Cutting them into small pieces helps them cook evenly and quickly.
