Why it works: Pepper and onion 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 ↓
Vermicelli Soup
Ingredients
Directions
In a pot, combine the knuckle of lamb, veal, and enough water to cover them well.
Cook until the meat is tender, then season with salt, pepper, herbs, and add the small onion and Worcestershire sauce.
Boil the vermicelli in a separate pot until tender, then strain the soup from the meat.
Add the cooked vermicelli to the soup, let it boil well, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vermicelli
- Forms the noodles that give the soup its body and bulk when cooked until tender.
- Lamb knuckle
- Releases collagen and flavor into the water as it simmers, enriching the broth.
- Veal
- Adds meat flavor and gelatin to the broth during long, gentle simmering.
- Worcestershire sauce
- Adds savory, tangy depth to the broth.
The step that matters
Cook the meat until tender before adding the vermicelli. Meat simmered gently in water needs time for its connective tissue to break down into gelatin, which gives the broth body. Adding the noodles too early or boiling hard can leave the meat tough and the broth cloudy.
