Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef kidney
- Provides the main body of the dish, becoming tender when stewed slowly.
- Lemon juice
- Adds acidity that brightens the rich, savoury flavour of the kidney.
The step that matters
Stew the diced kidney gently. Kidney is a tough, dense meat, so long gentle stewing breaks down its connective tissue. Boiling vigorously can toughen the proteins and make it chewy.
Swap the lemon
How well each one fits the dish's main ingredients (beef, parsley, pepper, mushroom):
- Lemonthe original
- Limefits about as well
- Avocadofits less well
- Cherryfits less well
Fit is the average pairing score against beef, parsley, pepper, mushroom. Candidates are from the same food group and used in at least 100 recipes.
