Why it works: Pepper and flour are a kitchen classic. They rank in the top 19% of all ingredient pairs, and cooks put them together in 50,459 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bacon
- Renders fat for frying and adds savory, smoky flavor to the dish.
- Liver
- Main protein; its texture softens and firms as it cooks through.
- Flour
- Coats the liver so it browns during frying and holds a crust.
The step that matters
Drying the liver before coating. Surface moisture stops flour from sticking evenly and turns the coating gummy, while a dry surface lets it brown and crisp in the hot fat.
