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 Liver and Bacon
Ingredients
Directions
Prepare
Cut the liver into thin slices and match the number of bacon slices to liver slices.
Fry the bacon first and place it on a hot dish.
Cook the liver
Fry the liver in the bacon fat, seasoning with pepper and salt.
Dredge the liver with a little 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 and serve
Pour off the bacon fat.
Add butter and dredge the butter in flour.
Add lemon juice and water.
Bring the mixture to a boil.
Pour the sauce into the center of the dish.

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
- Calf's liver
- Forms the main body of the dish, cooked to be tender when sliced thin and fried.
- Bacon
- Provides rendered fat for frying the liver and adds salty, smoky flavor.
- Flour
- Lightly coats the liver and thickens the pan sauce as it cooks with the fat and liquid.
- Butter
- Adds richness and flavor to the pan sauce, thickened with flour.
- Lemon juice
- Adds acidity that brightens the rich liver and bacon and balances the sauce.
The step that matters
Turn the liver occasionally to prevent burning. Thin liver slices cook quickly, and sugars and proteins on the surface brown fast in hot fat. Turning them evenly keeps the outside from scorching before the inside is done, and keeps the texture tender rather than tough.
