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 Pudding
Ingredients
Directions
The book says “a good oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Roll the crust to ½ inch thick and line a well‑greased basin with it.
Remove the hard core from the kidney, wash it in vinegar and water, and cut it into nearly 1‑inch square pieces.
Assemble and bake
Add bacon or pork fat if using, and season well.
Optionally, roll the kidney pieces in flour or thicken the gravy.
Add lemon juice or vinegar to tenderize and flavor the pudding.
Pour plain stock over the kidney and cover with the crust.
Bake in a moderate oven at 350°F (175°C) until cooked through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cow's kidney
- Forms the meat filling, becoming tender and rich-flavored as it cooks slowly in the pudding.
- Suet crust
- Encloses the filling and bakes into a sturdy, savory crust that holds in moisture.
- Plain stock
- Provides liquid that keeps the kidney moist and forms the gravy as it cooks.
- Fat bacon or salt pork
- Adds fat and savoriness that keeps the meat from drying out during baking.
The step that matters
Baking until cooked through. Kidney is dense and can turn tough if underdone or overcooked. Baking gently at a moderate oven heat lets the meat cook through while staying tender and the crust set.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (pepper, pork, lemon):
- Capsicumfits better
- Spinachfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against pepper, pork, lemon. Candidates are from the same food group and used in at least 100 recipes.
