Boiled Potatoes

Ingredients

Directions

Prepare

  1. Peel old potatoes. Soak new potatoes in cold water for 1–2 hours before cooking.

  2. For new potatoes, scrape the skin off before boiling. Leave 5–6 small ones in the kettle.

Boil and drain

  1. Place the potatoes in boiling water with 1 teaspoon of salt per quart of water.

  2. Drain the water and shake the potatoes near an open window or door.

  3. Return the potatoes to the heat for a few moments before serving.

Make the sauce and serve

  1. Break the small potatoes with a potato masher, then add ½ pint of milk, 1 tablespoon of flour mixed with 2 ounces of butter, and ½ teaspoon of salt.

  2. Thicken the mixture and pour it over the potatoes before serving.

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

What each ingredient does

Potatoes
Provide the starchy body of the dish, which softens when boiled.
Milk
Adds moisture and creaminess to the mashed small potatoes and sauce.
All-purpose flour
Thickens the milk mixture as it heats, giving the sauce body.
Butter
Adds richness and fat, smoothing the flour-thickened sauce.

The step that matters

Thicken the mixture. Flour must be cooked in the hot liquid so its starch swells and thickens the sauce; adding it raw or undercooking it leaves a floury, thin result.

Swap the potato

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

  1. Potatothe original
  2. Arrowrootfits about as well
  3. Leekfits less well
  4. Shallotfits less well

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