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 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 and roll in cracker dust.
Broil the coated slices, turning often, for about 8 minutes.
Add a few drops of the deviled sauce on each slice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Adds fat and richness, carrying the seasonings and helping the coating brown.
- Mustard
- Adds sharp, pungent flavor that cuts the richness of the kidneys.
- Lemon juice
- Adds acidity that brightens the buttery, savory sauce.
- Cracker dust
- Forms a crisp coating that browns under the broiler.
The step that matters
Melt the mixture gently without heating it. Heating the butter-based mixture too much can separate it into fat and solids, so it will not coat the slices evenly. Melting it gently keeps the emulsion smooth and cohesive.
