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 ↓
Spring Fruit Soup
Ingredients
Directions
Prepare the rhubarb
Peel and wash the rhubarb, then blanch it in water for 3-4 minutes.
Drain the rhubarb on a sieve and place it in a stewpan with sliced onions, carrot, ham, and butter.
Stew gently over low heat until tender.
Make the soup
Add the consommé and bread crumbs, then boil for about 15 minutes.
Skim off any fat, season with salt and Cayenne pepper, and pass through a fine sieve.
Serve
Serve with fried bread.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rhubarb
- Forms the main body of the soup and, once stewed, gives it its tart flavour and smooth texture.
- Butter
- Adds fat that carries flavour and gives the stewed vegetables a rich mouthfeel.
- Bread crumbs
- Thicken the soup as they boil, giving it body.
- Consommé
- Serves as the liquid base, carrying the flavour of the soup.
- Onions
- Build savoury sweetness and aroma as they soften slowly in the pan.
The step that matters
Stew gently over low heat until tender. Low, gentle heat softens the rhubarb and aromatics without scorching the butter or sugars, so they break down evenly. Rapid boiling at this stage can catch on the base of the pan and leave a burnt taste.
Swap the rhubarb
How well each one fits the dish's main ingredients (onion, carrot, ham, butter, bread, pepper):
- Parsleyfits better
- Celeryfits better
- Thymefits better
- Rhubarbthe original
Fit is the average pairing score against onion, carrot, ham, butter, bread, pepper. Candidates are from the same food group and used in at least 100 recipes.
