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 ↓

Ingredients
Directions
Prepare the meats
Boil the lungs in water for a few minutes, then change the water and boil for another half hour.
Boil half of the liver until it can be grated easily.
Trim and mince the heart, half of the liver, and part of the lights, removing all skins and black parts.
Mince the beef-suet and onions.
Grate the other half of the liver.
Fill the bag
Mix the minced meat with the scalded small onions and the toasted oatmeal.
Season the mixture with pepper, salt, and cayenne.
Prepare a clean sheep's paunch, ensuring there are no thin parts.
Add the meat mixture to the bag with the beef-gravy or broth, leaving room for expansion.
Add lemon juice or vinegar, press out the air, and sew up the bag.
Boil
Prick the bag with a large needle when it first swells in the pot to prevent bursting.
Boil slowly for three hours if large.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oatmeal
- Absorbs liquid and gives the filling a firm, crumbly body.
- Beef-suet
- Adds fat that keeps the filling moist and rich as it cooks.
- Liver
- Adds depth of flavour and a dense, smooth texture when grated.
- Beef-gravy or strong broth
- Supplies moisture that keeps the filling juicy during long boiling.
- Lemon juice or vinegar
- Adds acidity that brightens the rich meats and balances their flavour.
The step that matters
Prick the bag when it first swells. As the contents heat, steam and air expand inside the bag. Pricking it when it first swells releases that pressure, so the paunch does not burst in the pot.
Swap the lemon
How well each one fits the dish's main ingredients (beef, onion, liver, pepper):
- Limefits better
- Lemonthe original
- Avocadofits about as well
- Grapefits less well
Fit is the average pairing score against beef, onion, liver, pepper. Candidates are from the same food group and used in at least 100 recipes.
