Potato Soup, & LA Creme

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. Peel and dice the potatoes and onion.

  2. Combine the potatoes, onion, and broth in a pot.

  3. Bring to a boil.

Cook and blend

  1. Reduce heat and simmer until the potatoes are tender, about 20 minutes.

  2. Blend the soup until smooth.

Finish

  2. Season with salt.

  3. Garnish with fresh herbs if desired.

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

What each ingredient does

Potatoes
Starch that breaks down when simmered and blended, giving the soup its thick body.
Heavy cream
Adds fat and richness, producing a smooth, velvety mouthfeel.
Chicken or vegetable broth
Liquid that cooks the potatoes and onion and carries the flavor of the soup.
Onion
Adds savory aromatic flavor as it softens in the broth.

The step that matters

Simmering until the potatoes are fully tender. Potatoes must be fully softened before blending; undercooked starch stays grainy and gives a rough, uneven texture instead of a smooth purée.
