Why it works: Onion and carrot are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 21,601 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases savory flavor and gelatin into the liquid, giving the broth body and depth.
- Bacon
- Adds fat and smoky, savory flavor that carries through the broth.
- Onion
- Contributes sweetness and aroma as it softens and browns in the pot.
- Carrot
- Adds mild sweetness and aroma to balance the savory beef.
The step that matters
Simmering until the ingredients stick to the bottom. Sticking means the meat, onion, and carrot are browning on the pan, which builds color and roasted flavor. If they scorch, the broth turns bitter, so stir and keep the heat low enough to avoid burning.

Fit is the average pairing score against beef, onion. Candidates are from the same food group and used in at least 100 recipes.
