Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Iiam and Liver
Ingredients
Directions
Prepare
Boil the liver and chop it finely.
If you don't have cold ham, buy a slice, boil it, and chop it.
Mix the chopped liver and ham with the soup stock.
Stir in the seasoning, eggs, and bread crumbs.
Steam and serve
Grease a Boston brown bread mold or a small tin pail with a tight-fitting lid.
Put the mixture into the mold, fit on the lid, and place it in a vessel of boiling water, ensuring the water does not reach the top of the mold.
Boil for 2 hours, then turn out and pour 1 cup of good drawn butter over it.

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 loaf and gives it a rich, meaty flavor.
- Ham
- Adds salty, savory flavor and firmness to the chopped mixture.
- Eggs
- Bind the chopped meats and bread crumbs so the loaf holds its shape when cooked.
- Fine bread crumbs
- Absorb liquid and give the loaf a tender, sliceable body.
The step that matters
Keep the water below the top of the mold. If boiling water reaches the lid or top of the mold, it can seep in and make the loaf waterlogged. Keeping the water level below the mold lets the mixture cook gently in steam and hold a firm texture.
Swap the onion
How well each one fits the dish's main ingredients (liver, ham, bread, egg, parsley, pepper):
- Carrotfits better

- Capsicumfits better
- Onionthe original
Fit is the average pairing score against liver, ham, bread, egg, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
