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.

Make the soup

  1. In a large pot, bring 1 quart of water to a boil.

  2. Add the diced potatoes, carrots, onions, and celery.

  3. Season with salt and pepper.

  4. Simmer until the vegetables are tender, about 20 minutes.

Finish and serve

  1. Stir in the butter before serving.

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

What each ingredient does

Potatoes
Break down slightly as they cook, giving the soup body and a starchy thickness.
Carrots
Hold their shape while softening, adding sweetness and color to the broth.
Onions
Soften and release sweet aromatic flavor into the broth as they simmer.
Celery
Contributes savory aroma and a mild crisp-tender texture to the soup.
Butter
Stirred in at the end to add richness and a smooth, rounded mouthfeel.
