Hashed Potatoes

Ingredients

Directions

Prepare

  1. Peel the baked potatoes, leaving the brown underskin.

  2. Chop the peeled potatoes very fine.

Make the mixture

  1. Combine the milk and butter in an iron pan.

  2. Season the mixture with pepper and salt.

  3. Heat the mixture until the butter melts and the milk is scalding hot.

Cook

  1. Add the chopped potatoes to the pan and cover the pan.

  2. Cook over low heat for 30 minutes, lifting the potatoes from the bottom of the pan occasionally to prevent burning. Do not stir.

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

What each ingredient does

Baked potatoes
Provide the starchy base that softens into the bulk of the hash brown mixture.
Milk
Adds moisture and creaminess, helping the potatoes cook into a soft, tender mass.
Butter
Adds fat for richness and flavor, and helps the mixture cook smoothly in the pan.

The step that matters

Cook over low heat without stirring. Stirring breaks the chopped potato into a paste and releases more starch, making it gummy. Covering on low heat cooks the potato gently, and occasionally lifting from the bottom keeps it from scorching while the base browns.

Swap the potato

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

  1. Potatothe original
  2. Capsicumfits about as well
  3. Tomatofits less well
  4. Asparagusfits less well

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