Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Vegetable Soup
Ingredients
Directions
Prepare the vegetables
In a pot, combine the chopped carrots, onions, potatoes, and cabbage.
Add just enough water to cover the vegetables and stew until tender.
Finish the soup
Once tender, add boiling water and simmer for 20 minutes.
In a bowl, rub a little flour into the butter, then stir in the eggs.
Add the milk and mix thoroughly.
Stir the mixture into the soup and boil for a few moments.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide sweetness, colour and body to the soup.
- Potatoes
- Break down as they cook, thickening the soup and adding body.
- Eggs
- Enrich and thicken the liquid as they set when stirred in.
- Milk
- Adds creaminess and moisture, mellowing the soup's texture.
- Butter
- Adds richness and fat, carrying flavour through the soup.
The step that matters
Stirring the egg mixture into the soup. Eggs set when heated, so they can curdle into lumps if added to very hot liquid too fast. Stirring the mixture in gradually and keeping the boil gentle helps it blend smoothly.
Swap the cabbage
How well each one fits the dish's main ingredients (carrot, onion, potato, butter, egg, milk):
- Leekfits better
