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 ↓
Stuffing for Heart
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the heart
Wash and dry the heart.
Stuff the heart with a mixture of bread crumbs, suet, egg, parsley, pepper, and salt, then sew it up.
Roast the heart at 400°F (200°C) for 30 to 45 minutes, depending on size.
Make the hash
Parboil the lights and half the liver, then mince them finely.
Stew the minced lights and liver in a little of the boiling liquid with a chopped onion, pepper, salt, ketchup, and a little flour for 30 minutes.
Slice the remaining liver, toss in flour, and fry with slices of bacon.
Serve
Place the roasted heart in the center of a hot dish, surround it with the hash, and garnish with alternating slices of liver and bacon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread crumbs
- Absorb moisture and bind the stuffing so it holds its shape while roasting.
- Suet
- Adds fat that keeps the stuffing moist and rich as it roasts.
- Egg
- Binds the stuffing together and helps it set during roasting.
- Liver (in the method)
- Provides a rich, savory meat base for the hash and garnish.
- Flour (in the method)
- Coats the liver and thickens the stewing liquid for the hash.
The step that matters
Roast the stuffed heart for the right time. Heart is dense and the stuffing is packed inside, so the time depends on size. Roasting too briefly leaves the centre underdone, while overlong roasting dries the meat and stuffing.
Swap the parsley
How well each one fits the dish's main ingredients (bread, egg, pepper):
- Parsleythe original
- Nutmegfits about as well
- Marjoramfits less well
- Sagefits less well
Fit is the average pairing score against bread, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
