Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Kidneys with Sherry
Ingredients
Directions
Prepare the kidneys
Drain the kidneys and cut them into small pieces.
Cover the kidneys with cold water and heat gently, ensuring the water does not boil.
Repeat this process three times.
Make the sauce
In a frying pan, melt the butter and stir in the flour until browned.
Gradually add the boiling stock or water, stirring with a wooden spoon until it boils for 3 minutes.
Add Worcestershire sauce, catsup, salt, pepper, and the kidneys. Stir until the kidneys are heated through.
Remove from heat, stir in the sherry, and serve garnished with chopped parsley.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Provide the main meat, which is gently heated in water to tenderize and mild the flavor.
- Flour
- Thickens the butter and stock into a smooth sauce as it cooks.
- Butter
- Adds richness and, when browned with the flour, a nutty flavor to the sauce.
- Sherry
- Adds a sweet, aromatic, slightly acidic note to the finished sauce.
- Worcestershire sauce
- Adds savory, tangy depth that seasons the sauce.
The step that matters
Gradually adding the boiling stock. Adding liquid slowly while stirring keeps the flour and butter mixture smooth, so lumps do not form. Boiling the sauce for 3 minutes fully cooks the flour, so it thickens properly and loses its raw taste.
Swap the parsley
How well each one fits the dish's main ingredients (butter, flour, sauce, pepper, sherry):
- Parsleythe original
- Capersfits about as well
- Thymefits about as well
- Nutmegfits about as well
Fit is the average pairing score against butter, flour, sauce, pepper, sherry. Candidates are from the same food group and used in at least 100 recipes.
