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 Liyer and Bacon
Ingredients
Directions
Prepare
Cut the liver into thin slices.
Cut the same number of bacon slices as liver slices.
Cook
Fry the bacon first and place it on a hot dish.
Fry the liver in the bacon fat, seasoning with pepper and salt, and dredging with a little flour. Turn the liver occasionally to prevent burning.
Once cooked, 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 a small piece of butter, a little flour, lemon juice, and water. Bring to a boil and pour the sauce in the middle of the dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Liver
- Forms the main body of the dish, cooking to a tender, browned texture when fried.
- Bacon
- Its fat is used to fry the liver, adding savory flavor and aroma.
- Flour
- Dredging coats the liver so it browns, and a little thickens the sauce.
- Butter
- Adds richness and fat to the pan sauce.
- Lemon juice
- Adds acidity that brightens the rich liver and fat in the sauce.
The step that matters
Frying the liver. Liver turns dry and grainy when overcooked, and it can burn on the surface before the center is done. Turning it occasionally and keeping heat moderate helps it brown evenly while staying tender.
“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.
