Why it works: Mustard and lemon match in chemistry and in kitchens. They rank in the top 11% of all ingredient pairs, and cooks put them together in 3,816 recipes. Both carry eucalyptol, which smells eucalyptus, herbal. The science ↓
Deviled Kidneys
Ingredients
Directions
Prepare
Slice the kidneys and remove hard centers and fat.
In a bowl, beat together the butter, mustard, paprika or cayenne, salt, and lemon juice until creamy.
Melt the mixture gently without heating it.
Coat and broil
Coat each kidney slice with the mixture, then roll in cracker dust.
Broil the coated slices, turning often, for about 8 minutes.
Serve with a few drops of the deviled sauce on top.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kidneys
- Provide the meat that is coated and broiled as the main dish.
- Butter
- Carries the seasonings and adds richness and moisture to the coating.
- Mustard
- Adds sharp, tangy flavor that cuts through the richness of the kidneys.
- Cracker dust
- Forms a crisp, browned crust on the outside of each slice when broiled.
The step that matters
Melt the mixture gently without heating it. The record's wording is contradictory: melting implies heat, yet the instruction says not to heat it. Melting butter too hot can separate it and scorch the milk solids, so keep it just soft and spreadable.
Swap the mustard
How well each one fits the dish's main ingredients (butter, lemon):
- Shallotfits better
- Asparagusfits better
- Leekfits better
- Mustardthe original
Fit is the average pairing score against butter, lemon. Candidates are from the same food group and used in at least 100 recipes.
