Why it works: Beef and tomato are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 5,448 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
- Veal knuckle
- Bones and connective tissue release gelatin, giving the broth body and a rich mouthfeel.
- Beef
- Simmered meat adds savory depth and meaty flavor to the broth.
- Split peas
- They break down while boiling, thickening the soup and adding body.
- Tomatoes
- Add acidity and a tangy sweetness that balances the rich broth.
- Flour
- Starch thickens the liquid once stirred in and heated.
The step that matters
Mixing in the flour. Flour added to hot liquid can clump unless it is dispersed evenly first. Starch needs to be fully incorporated to thicken smoothly, and straining through a fine sieve catches any lumps that remain.
Swap the peas
How well each one fits the dish's main ingredients (veal, beef, tomato, flour, sauce):
- Beansfits better
- Lentilsfits better
- Chestnutfits better
- Peasthe original
Fit is the average pairing score against veal, beef, tomato, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
