Why it works: Beef and onion are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Turtle Soup, Mock
Ingredients
Directions
Make the broth
In a large stewpan, combine veal, beef, butter, onions, and bouquet garni.
Cook over medium heat until lightly browned.
Dredge in flour, then add stock and Madeira, seasoning with salt and pepper.
Bring to a boil, then add the boned calf's head and simmer for 3 hours.
Strain the broth and simmer for an additional hour, skimming frequently.
Finish and serve
Remove the head, cut it into 1-inch squares, and return it to the soup before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the broth as it cooks, giving the soup body.
- Butter
- Carries the flavour of the onions and meats and helps them brown.
- Calf's head
- Adds gelatin, which gives the soup a rich, silky body.
- Madeira
- Adds sweetness and depth of flavour to the broth.
The step that matters
Dredging the meat in flour before adding liquid. Flour coating on browned meat dissolves into the stock and thickens it evenly. Adding liquid without first coating and cooking the flour can leave lumps and a thin, starchy-tasting broth.
