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 ↓
Bran Stock
Ingredients
Directions
Put a large handful of bran into 1 quart of water.
Boil and then simmer until the quantity is reduced to half.
For a thicker soup, add onions, coarse sea salt, black pepper, and a few vegetables.
For a sweet version, mix in molasses or honey.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bran
- Thickens the broth as it simmers, giving the soup its body and texture.
The step that matters
Simmering until reduced by half. Reducing the liquid concentrates the flavor and thickens the soup. Stopping too early leaves it thin and watery, while boiling too hard can scorch the bran on the bottom of the pot.
