Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Prepare
Wash the heart thoroughly inside and out.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heart
- Forms the main meat and becomes tender with long, moist cooking.
- Broken bread
- Absorbs liquid and gives the stuffing body and a soft texture.
- Fat
- Browns the surface, adding colour and savoury flavour.
- Onion
- Adds aromatic sweetness and moisture to the bread stuffing.
The step that matters
Simmer until tender. Heart is a tough, muscular meat that needs long, gentle, moist cooking to break down its connective tissue. Rapid boiling can toughen the surface and leave the centre firm, so keep the water at a gentle simmer.
Swap the onion
How well each one fits the dish's main ingredients (bread, pepper, flour):
