Catskill Potatoes

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Peel and slice the potatoes, then soak them in cold water for about an hour.

Assemble

  1. Butter a deep dish and layer the potatoes, sprinkling each layer with salt, pepper, and bits of butter.

  2. Add chopped onion for extra flavor if desired.

  3. Cover the entire dish with milk.

Bake

  1. Bake in a 300°F (150°C) oven for 2 to 3 hours.

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

What each ingredient does

Potatoes
Form the bulk of the dish and become tender and creamy as they bake.
Butter
Adds richness and moisture, and helps the top brown lightly.
Milk
Covers the layers and turns into a creamy sauce as it cooks slowly.
Chopped onion
Adds savory aroma and a mild sweetness as it softens during baking.

The step that matters

Covering the layers with milk. Milk must fully cover the potatoes so they cook evenly in the slow oven. Exposed potato pieces can dry out and darken, while the milk gently thickens into a sauce.

Swap the onion

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

  1. Capsicumfits better
  2. Asparagusfits about as well
  3. Tomatofits about as well
  4. Onionthe original

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