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 the heart. Dry the heart.
Mix bread crumbs, suet, egg, parsley, pepper, and salt in a bowl.
Stuff the heart with the mixture. Sew the heart closed.
Roast and make the hash
Roast the heart at 400°F (200°C) for 30 to 45 minutes, depending on size.
Parboil the lights and half the liver. Mince the parboiled lights and half the liver finely.
Stew the minced lights and liver in their cooking liquid with onion, pepper, salt, ketchup, and a little flour for 30 minutes.
Fry the liver and serve
Slice the remaining liver. Dust the sliced liver with flour.
Fry the floured liver with bacon slices.
Serve the heart in the center of a hot dish, surrounded by the hash and garnished with liver and bacon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Binds the stuffing so it holds together around the heart.
- Bread crumbs
- Absorb moisture and give the stuffing body and structure.
- Suet
- Adds fat that keeps the stuffing moist and rich during roasting.
- Flour
- Dusts the liver and thickens the stewed hash as it cooks.
- Onion
- Adds savoury depth and aroma to the stewed hash.
The step that matters
Roast the heart at 400°F (200°C) for 30 to 45 minutes, depending on size.. Heat must reach the centre of the thick muscle without drying the outside. Judging by size, not just time, helps keep the meat tender and the stuffing cooked through.
Swap the onion
How well each one fits the dish's main ingredients (bread, egg, parsley, pepper, ketchup, flour):
- Shallotfits better
- Capsicumfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against bread, egg, parsley, pepper, ketchup, flour. Candidates are from the same food group and used in at least 100 recipes.
