Why it works: Pepper and lemon match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Hassenpfeffer, or Sour Rabbit
Ingredients
Directions
Marinate
Place the cut rabbit in a crock and cover with vinegar.
Add sliced onions, whole cloves, black pepper, and salt.
Let it stand overnight.
Cook and thicken
In the morning, boil the mixture, adding enough water to prevent it from cooking dry.
Heat lard in a skillet. Add flour. Brown to a dark color while stirring constantly.
Stir the browned mixture into the rabbit and boil for about ten minutes.
Add lemon slices if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rabbit
- Main protein that becomes tender during the long vinegar soak and simmer.
- Vinegar
- Acidity that sours the meat and helps tenderize it during the overnight soak.
- Lard
- Fat that carries flavor and helps the flour brown in the skillet.
- Flour
- Browned in fat, it thickens the cooking liquid and adds a toasted, nutty flavor.
- Onions
- Sweetness and aromatic flavor that mellow into the sour marinade.
The step that matters
Browning the flour in lard. Flour must be stirred constantly over heat until dark brown; if it scorches it turns bitter, and if pale it will not add the deep color and flavor or thicken the sauce well.
Swap the lemon
The recipe marks lemon as optional. How well each one fits the dish's main ingredients (rabbit, vinegar, onion, clove, pepper, flour):

- Lemonthe original
- Mangofits about as well
- Avocadofits about as well
Fit is the average pairing score against rabbit, vinegar, onion, clove, pepper, flour. Candidates are from the same food group and used in at least 100 recipes.
