Why it works: Mushroom and sherry are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,176 recipes. Both carry 2-methoxy-4-methylphenol, which smells smoky, clove. The science ↓
Stewed Kidneys
Ingredients
Directions
Prepare the kidneys
Split the kidneys in half.
Carefully trim the sinews and fat inside the kidneys.
Cut the kidneys into small pieces.
Place the pieces in a pan covered with cold water.
Heat on moderate fire until almost boiling.
Drain the water.
Cover with fresh cold water.
Repeat this process two more times without boiling.
Make the sauce and finish
In a frying pan, melt the butter until brown.
Add the flour and boiling water or stock.
Stir constantly until it boils.
Add Worcestershire sauce, mushroom catsup, salt, pepper, and the kidneys.
Stir until the kidneys are thoroughly heated.
Remove from heat and add sherry.
Serve immediately.

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 meat, which becomes tender and mild after repeated changes of water.
- Butter
- Fat that is browned to add rich, nutty flavour to the sauce.
- Flour
- Thickens the stock into a smooth sauce when stirred and brought to a boil.
- Sherry
- Added off the heat to contribute aroma and a sweet, mellow acidity.
The step that matters
Repeated changes of cold water. Kidneys carry a strong, ammonia-like taste. Starting in cold water, bringing it only to almost boiling, and renewing the water several times draws out these compounds and keeps the meat from toughening. Boiling hard would firm the proteins and make the kidneys tough.
