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 ↓
Carrot Cream Soup
2 quarts of soupIngredients
Directions
Prepare the carrots
Wash, scrape, and slice enough carrots to fill a pint bowl.
Boil the carrots in 1 quart of boiling water with a little salt until soft enough to pass through a sieve.
Make the soup
In a separate pan, mix the flour and butter until bubbling.
Stir this mixture into 1 quart of hot milk and the carrot pulp.
Add enough hot water to make 2 quarts of soup.
Season with 1 teaspoon of salt and a pinch of cayenne pepper.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide the main flavour and body of the soup once boiled and sieved into a pulp.
- Flour
- Thickens the soup as it cooks with the butter and milk, giving it a creamy texture.
- Butter
- Cooks with the flour to form a roux and adds richness to the soup.
- Milk
- Adds creaminess and body, mellowing the carrot flavour.
The step that matters
Mixing the flour and butter until bubbling. Cooking flour in butter until bubbling forms a roux. If it is not cooked enough, the soup can taste pasty; if it is stirred in unevenly, lumps form. Stirring the hot mixture into the hot milk and carrot pulp gradually keeps the soup smooth.
Swap the carrot
How well each one fits the dish's main ingredients (flour, butter, milk, pepper):
- Potatofits better
- Capsicumfits better
- Chivefits about as well
- Carrotthe original
Fit is the average pairing score against flour, butter, milk, pepper. Candidates are from the same food group and used in at least 100 recipes.
