Why it works: Barley and celery work together. They rank in the top 6% of all ingredient pairs, and cooks put them together in 571 recipes. Both carry 2-methoxy-4-vinylphenol, which smells clove, smoky. The science ↓
Celery Soup
Ingredients
Directions
Prepare the barley
Soak the pearl barley in cold water overnight.
Make the soup

Rub the mixture through a sieve and combine it with the remaining bouillon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl barley
- Thickens the soup and gives it a hearty body as it softens and breaks down.
- Egg yolks
- Enrich and thicken the soup, giving it a smooth, velvety texture.
- Cream
- Adds richness and fat, softening the flavour and smoothing the texture.
- Celery
- Provides the main flavour and, once cooked and sieved, most of the soup's body.
The step that matters
Gradually pour in the soup while whisking continuously. Egg yolks scramble if they get too hot too fast. Adding hot soup slowly while whisking gently tempers the yolks, so the mixture thickens smoothly instead of curdling.
Swap the celery
How well each one fits the dish's main ingredients (barley, egg, cream, bread):
- Nutmegfits better
- Capersfits about as well
- Celerythe original
- Parsleyfits about as well
Fit is the average pairing score against barley, egg, cream, bread. Candidates are from the same food group and used in at least 100 recipes.
