Why it works: Flour and pepper 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 ↓
Liver and Bacon
Ingredients
Directions
Prepare the liver
Pour boiling water over the liver slices and let them stand for 5 minutes.
Wipe the liver slices dry.
Coat the liver slices thickly with flour.
Cook the liver and bacon
Cook the bacon in a frying pan over medium heat for 3 minutes.
Add lard if needed.
Add the liver slices to the hot bacon and fry for a few minutes on one side, then turn and fry the other side until browned.
Pour in enough boiling water to half-cover the liver.
Season with salt and pepper.
Cover tightly and let simmer gently for 20 to 30 minutes.
Make the sauce and serve
Remove the liver and bacon to a hot dish.
Boil the remaining liquid in the pan, stirring.
Add boiling water if it has reduced too much.
Pour the sauce over the liver and bacon before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Provides the meat that is browned on the outside and becomes tender after simmering.
- Bacon
- Renders fat into the pan for frying and adds savoury, salty flavour to the sauce.
- Flour
- Coats the liver so it browns during frying and helps thicken the sauce.
The step that matters
Simmering covered after browning. Simmering gently in a tightly covered pan with a little liquid keeps the liver tender. Boiling hard or overcooking makes liver tough and dry, so keep the heat low.
