Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Kidney Pie
Ingredients
Directions
Prepare
Slice the veal kidneys about ¼ inch thick.
Scald, clean, bone, and slice the calf's foot in the same way.
Season the kidney and calf's foot slices with salt, cayenne, and cloves.
Assemble and bake
Layer the kidney slices in a pie dish, sprinkle with minced ham, add calf's foot, more ham, and kidney slices again.
Fill with yolks of hard-boiled eggs and force-meat balls.
Pour in veal stock mixed with lemon juice and sherry.
Cover with pie crust and bake for 1.5 hours.
Serve
Serve cold.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal kidneys
- Provide the main meat body and rich, savory flavor of the pie.
- Calf's foot
- Releases gelatin as it cooks, helping the filling set firm when chilled.
- Veal stock
- Adds moisture and savory depth that keeps the filling from drying out in the oven.
- Hard-boiled egg yolks
- Add a rich, creamy texture that softens the meat's firmness.
- Sherry or madeira
- Adds acidity and aromatic sweetness that balance the rich meats.
The step that matters
Cover with pie crust and bake for 1.5 hours. The long, enclosed bake must cook the kidney fully while keeping the filling moist. Too high heat or too short a time leaves the meat tough or underdone, and the calf's foot needs the full time to release enough gelatin to set the filling when cold.
Swap the clove
How well each one fits the dish's main ingredients (veal, pepper, ham, egg, meat, lemon, sherry):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Clovethe original
Fit is the average pairing score against veal, pepper, ham, egg, meat, lemon, sherry. Candidates are from the same food group and used in at least 100 recipes.
