Ingredients
Directions
Prepare the beans
Soak the kidney beans overnight.
Boil the beans until tender but not breaking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidney beans
- Form the main body of the dish and give it a soft, starchy texture when cooked through.
- Clarified dripping
- Adds fat for frying and a rich, savoury flavour that coats the beans.
- Onion
- Adds aromatic sweetness and savoury depth as it softens in the hot fat.
The step that matters
Let the beans dry before frying. Beans that stay wet will cool the hot fat and steam instead of frying, so they do not take on flavour or colour. Draining and drying them first helps the dripping coat them well.
Swap the kidney beans
How well each one fits the dish's main ingredients (beef, onion, parsley, pepper):
- Black-eyed peafits better
- Chickpeafits better
- Beansfits better
- Kidney beansthe original
Fit is the average pairing score against beef, onion, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
