Why it works: Liver and pork are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 1,606 recipes. Both carry 1-nonanal, which smells fatty, waxy. The science ↓
Baked Liver
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Boil the calf's liver for 1.5 hours or until cooked.
Chop the liver finely with the salt pork and onions.
Season the mixture with butter, coarse sea salt, and black pepper.
Shape and bake
Form the mixture into a loaf and place thin strips of salt pork on top.
Bake in a 350°F (175°C) oven for 1 hour.

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 bulk of the loaf and gives it its rich, meaty flavor.
- Salt pork
- Adds fat and savory flavor, helping keep the loaf moist.
- Onions
- Add sweetness and aroma as they blend into the chopped mixture.
- Butter
- Adds richness and moisture to the chopped mixture.
The step that matters
Baking the loaf. Liver is lean, and its proteins tighten and turn dry and grainy when overcooked. Since the liver is already cooked, the oven time mainly sets the loaf and browns the top, so it should not be baked longer than the recipe states.
Swap the onion
How well each one fits the dish's main ingredients (liver, pork, butter, pepper):
- Potatofits about as well
- Capsicumfits about as well
- Onionthe original
- Tomatofits about as well
Fit is the average pairing score against liver, pork, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
