Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 34,122 recipes mention both. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ingredients
Directions
Flour the sliced onions well and place them in a skillet with the hot lard.
Add the chopped tomatoes and let everything brown without frying.
Add the meat of your choice and cook slowly.
Occasionally add hot water if the gravy gets too thick.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Break down and brown to give the gravy sweetness and body.
- Lard
- Fat that carries heat and helps the onions brown evenly.
- Tomatoes
- Add acidity and moisture that deepen the sauce's flavor as they cook down.
- Meat
- Adds savory flavor and richness to the gravy as it cooks slowly.
The step that matters
Browning the onions and tomatoes without frying. Flouring the onions and letting them brown slowly in the hot lard builds color and flavor through browning reactions. Cooking too hot can scorch the flour and turn the sauce bitter, so the heat needs to stay moderate.

Fit is the average pairing score against tomato, meat, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
