Why it works: Carrot and pepper match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Vegetable Soup with Eggs
Ingredients
Directions
Make the stock
In a large pot, combine the beef, veal, marrow bones, and all the vegetables with the water.
Bring to a boil and then simmer slowly for 5 to 6 hours. If the liquid reduces by more than one-third, add boiling water.
Once the meat is tender and the vegetables are broken down, strain the mixture.
Pulp the vegetables through a colander, cool the stock, and skim off any fat.
Season the stock well and reserve a portion for later use.
Serve
Reheat the stock, skim again, and pour into a tureen.
Poach the yolks of the eggs and place them on the surface of the soup before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Gives the stock its deep, meaty flavour as it simmers for hours.
- Veal
- Adds gelatin from the scrag, giving the stock body and a richer mouthfeel.
- Marrow bones
- Release gelatin and fat during long simmering, adding richness and body to the broth.
- Tomatoes
- Add acidity and savoury depth to the stock, and pulp to thicken the soup.
- Eggs
- Yolks poached on top add richness and a creamy texture to the soup.
The step that matters
Simmering the stock slowly. A gentle simmer keeps the stock clear and extracts collagen from the bones and meat without emulsifying fat into it. A rolling boil makes the broth cloudy and greasy.
Swap the peas
How well each one fits the dish's main ingredients (beef, veal, carrot, onion, tomato, corn, pepper):
- Beansfits better
- Chickpeafits better
- Sesamefits better
- Peasthe original
Fit is the average pairing score against beef, veal, carrot, onion, tomato, corn, pepper. Candidates are from the same food group and used in at least 100 recipes.
