Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Cream of Celery Soup

Ingredients

Directions

Make the stock

  1. Cook the celery in boiling water until very soft.

  2. Press the cooked celery through a strainer to obtain 4 cups of stock.

Finish the soup

  1. In a separate pot, heat the milk with onion juice and add to the celery stock.

  2. In a small bowl, mix the flour with a little water to create a smooth paste, then stir it into the soup.

  3. Add butter and season with pepper before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Celery
Provides the main flavor and body of the soup as it is cooked and strained.
Flour
Thickens the soup as it heats, giving it a smoother, creamier texture.
Milk
Adds richness and a creamy body to the thinned celery stock.
Butter
Adds fat for a rounder flavor and smoother mouthfeel.

The step that matters

Mixing the flour into the soup. Flour added dry or in lumps will clump and stay grainy. Mixing it into a smooth paste with a little water first lets it disperse evenly so the soup thickens smoothly.

Swap the onion

How well each one fits the dish's main ingredients (celery, flour, milk, pepper, butter):

  1. Carrotfits better
  2. Potatofits better
  3. Capsicumfits better
  4. Onionthe original

Fit is the average pairing score against celery, flour, milk, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
