Why it works: Meat and onion are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 6,364 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Stocks and Sauces
Ingredients
Directions
Make the stock
Combine 1 pound of meat with 1½ pints of water in a pot.
Add a bay leaf if desired and bring to a simmer.
Simmer for 4 to 6 hours, skimming off fat as it cools.
Color and finish
For coloring, make caramel by melting ½ pound of sugar in a copper pot until light brown, then add ½ pint of water and reduce to syrup.
Alternatively, fry onions until very brown, pound them, and stir into the stock.
Season to taste before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat (beef or veal)
- Releases flavor and gelatin into the water as it simmers, giving the stock its body and savor.
- Sugar (in the method)
- Caramelizes to a deep brown, adding color to the stock with a slightly bitter, toasted note.
- Browned onions
- Add deep brown color and a toasted, savory flavor when fried very dark and stirred in.
The step that matters
Skimming fat as the stock simmers. Fat that is left in the stock turns greasy and can cloud the liquid. Skimming as it cools lifts off the fat so the stock stays clear and clean-tasting.
