Escalloped Potatoes

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare and layer

  1. Peel and slice the potatoes.

  2. In a pot, layer the potatoes with butter, salt, and pepper.

  3. Slice the onion and add it to the mixture.

Add milk and bake

  1. Sprinkle bread crumbs on top.

  2. Pour the milk over everything.

  3. Heat the mixture, then bake at 400°F (200°C) for 2.5 hours using both hot radiators.

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 soften into a tender, starchy body as they bake.
Milk
Provides the liquid that cooks around the potatoes, creating a creamy, moist sauce.
Butter
Adds fat for richness and helps the top brown during baking.
Onion
Softens as it bakes, adding savory aroma and mild sweetness.
Bread crumbs
Form a top layer that browns and adds a light, crisp texture.

The step that matters

Bake long enough for the potatoes to soften. Potato starch needs sustained heat to swell and turn tender. Stopping early leaves the slices firm and the sauce thin, so the full baking time matters.

Swap the onion

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

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

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