Why it works: Pepper and parsley 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 ↓
Baked Liver
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 300°F (150°C).
Season the calf's liver with pepper, coarse sea salt, and chopped parsley.
Lard the liver with strips of pork or bacon.
Bake
For added flavor, braise with small vegetables and meat trimmings underneath the liver.
Bake for two hours.
Baste the liver frequently while baking.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's liver
- Is the main meat, cooked gently so it stays moist and tender.
- Pork or bacon strips
- Fat laced through the liver melts during baking, adding moisture and savory flavor.
- Small vegetables
- Braised underneath the liver, they add aroma and flavor to the pan juices.
The step that matters
Baste the liver frequently while baking. Liver is lean and dries out easily over a long bake. Spooning the pan juices over the surface keeps it moist and helps it stay tender instead of firm and grainy.
Swap the parsley
How well each one fits the dish's main ingredients (liver, pepper, pork, meat):
- Thymefits better
- Sagefits better
- Marjoramfits about as well
- Parsleythe original
Fit is the average pairing score against liver, pepper, pork, meat. Candidates are from the same food group and used in at least 100 recipes.
