Why it works: Clove and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 17,451 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓
Stewed Kidneys
Ingredients
Directions
Prepare and fry
Skin the kidneys, split them in two, remove the core, wash, and dry.
Roll the kidneys in flour and fry quickly in butter.
Stew and serve
Place the kidneys in a pan with hot stock, add mushrooms, onion, and seasoning.
Simmer for half an hour.
Blend the flour with a little cold water or stock.
Pour the hot stock over the mixture, return to the pan, and boil thoroughly.
Add sherry, dish the kidneys, strain the gravy over, and garnish with small potato balls or boiled macaroni.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sheep's kidneys
- The main ingredient, which becomes tender with gentle simmering in liquid.
- Flour
- Thickens the gravy as its starch swells when heated in liquid.
- Butter
- Fat for frying the kidneys, adding richness and browning on the surface.
- Onion
- Adds aroma and gentle sweetness as it cooks in the stock.
- Mushrooms
- Add savoury, earthy depth to the stewing liquid.
- Sherry
- Adds acidity and aroma that brighten the finished gravy.
The step that matters
Blending the flour with cold liquid before adding hot stock. Flour starch clumps if dropped into hot liquid directly. Blending it first with cold water or stock lets the particles separate, so the hot stock thickens the gravy smoothly once it is boiled.
Swap the onion
How well each one fits the dish's main ingredients (flour, sherry, butter, mushroom, clove, pepper):
- Shallotfits better
- Capsicumfits better
- Leekfits better
- Onionthe original
Fit is the average pairing score against flour, sherry, butter, mushroom, clove, pepper. Candidates are from the same food group and used in at least 100 recipes.
