Parsnip Soup No. 2

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.

Prepare

  1. Peel and chop the parsnips and onion.

Make the soup

  1. In a pot, melt the butter and sauté the onion until translucent.

  2. Add the parsnips and water, then bring to a boil.

  3. Simmer until the parsnips are tender, about 20 minutes.

  4. Blend the mixture until smooth, then stir in the milk.

Season and serve

  1. Season with salt and pepper before serving.

What each ingredient does

Parsnips
Form the main body of the soup and, once cooked and blended, give it its thick texture.
Onion
Sautéed in butter until translucent, it adds a mild sweetness and savory base.
Butter
Carries the onion's flavor into the pot and adds richness to the soup.
Milk
Stirred in after blending, it adds creaminess and softens the soup's flavor.
