Potato Soup with Whipped Cream

Ingredients

Directions

Prepare the soup base

  1. Peel and boil the potatoes until tender.

  2. In a double boiler, scald the milk.

  3. In a bowl, rub together the butter and flour until smooth.

  4. Add the butter‑flour mixture to the hot milk and stir gently until it melts and thickens slightly.

  5. Add the parsley and onion juice, cover, and cook for 10 minutes.

Finish and serve

  1. Mash the boiled potatoes and blend them with part of the thickened milk.

  2. Press the mixture through a sieve and combine it with the remaining milk in the double boiler.

  3. Season with salt and pepper, cover, and cook for an additional 5 minutes.

  4. Whip the heavy cream until it forms stiff peaks.

  5. Serve the soup in cups, filling them halfway, and top each with a heaping tablespoon of whipped cream, then sprinkle with a dash of paprika.

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

What each ingredient does

Potatoes
Become a starchy body that thickens and gives the soup its smooth, creamy texture when pressed.
Milk
Forms the liquid base of the soup, carrying the other ingredients and giving richness.
Butter and flour
Form a roux that thickens the hot milk and gives the soup body.
Heavy sweet cream
Whipped into stiff peaks to add a light, rich topping with fat for texture.

The step that matters

Stirring the butter‑flour mixture into the hot milk. Flour clumps if added raw or unevenly, so it must be rubbed smooth first and stirred gently into hot milk so the starch swells evenly and thickens the soup without lumps.

Swap the onion

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

  1. Chivefits better
  2. Carrotfits better
  3. Leekfits better
  4. Onionthe original

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