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 ↓

Ingredients
Directions
Make the broth
In a pot, cover the knuckle of lamb and veal with water and cook until tender.
Season the broth with salt, pepper, herbs, and the small onion.
Add Worcestershire sauce to the broth.
Finish the soup
Boil the vermicelli in a separate pot until tender, then strain it.
Combine the strained soup with the cooked vermicelli and let it boil well before serving.
