Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

  1. Heat olive oil in a pot over medium heat.

  2. Add chopped onion and sauté until translucent.

  3. Add green peas and vegetable broth.

  4. Bring to a boil, then reduce heat and simmer for 20 minutes.

  5. Blend the soup until smooth, then season with salt and pepper.

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

What each ingredient does

Green peas
Form the body of the soup and give it its main flavor and color.
Vegetable broth
Provides the liquid that cooks the peas and sets the soup's consistency once blended.
Onion
Adds savory depth as it softens and turns translucent in the oil.
Olive oil
Carries the flavor of the onion and adds richness to the soup.

The step that matters

Blend the soup until smooth. Blending while the peas are fully cooked breaks down their cell walls to create a smooth, creamy texture. Under-cooked peas leave a grainy or starchy result that no amount of blending fully fixes.

Swap the peas

How well each one fits the dish's main ingredients (onion, olive, pepper):

  1. Black-eyed peafits better
  2. Sesamefits better
  3. Chickpeafits better
  4. Peasthe original

Fit is the average pairing score against onion, olive, pepper. Candidates are from the same food group and used in at least 100 recipes.
