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 ↓
Ham and Liver
Ingredients
Directions
Prepare
Boil the liver and chop it finely.
If you don't have cold ham, buy a slice.
Boil the ham slice 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 closely fitting top.
Put the mixture into the mold.
Fit the lid on the mold.
Set the mold in a vessel of boiling water, making sure the water does not come to the top of the mold.
Boil for 2 hours.
Turn out the mold.
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 dense, savoury body of the pudding.
- Eggs
- Bind the mixture and help it set firm when cooked.
- Bread crumbs
- Absorb liquid and give the pudding a soft, cohesive texture.
- Ham
- Adds salty, savoury flavour and meaty texture.
The step that matters
Keep the water below the top of the mold. If boiling water reaches the lid, it can seep in and make the pudding waterlogged, while a gentle, steady simmer cooks the egg-bound mixture evenly and keeps it moist and firm.
Swap the onion
How well each one fits the dish's main ingredients (liver, ham, bread, egg, parsley, pepper):

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.
