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 ↓
Calf's Liveb and Bacon
Ingredients
Directions
Prepare
Cut the liver into thin slices.
Match the number of bacon slices to the liver slices.
Cook the bacon and liver
Fry the bacon first and place it on a hot dish.
Fry the liver in the bacon fat, seasoning with pepper and salt, and lightly dredging with flour.
Turn the liver occasionally to prevent burning.
When done, arrange the liver around the dish with a piece of bacon between each slice.
Make the sauce
Pour off the bacon fat.
Add a small piece of butter.
Dredge the butter in a little flour.
Add lemon juice and water.
Bring the mixture to a boil.
Pour the sauce in the center of the dish.
Garnish with lemon slices or forcemeat balls if desired.

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
- Liver
- Its lean protein sets firm when fried, while a quick cook keeps it tender.
- Bacon
- Its fat fries the liver and adds salty, smoky flavour.
- Flour
- A light dusting helps the liver brown and thickens the pan sauce.
- Lemon juice
- Adds acidity that brightens the rich liver and fatty sauce.
The step that matters
Turn the liver occasionally. Liver is thin and lean, so it dries out and toughens quickly over high heat. Turning it regularly promotes even browning and keeps the inside tender instead of burnt on the outside.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
