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

  1. Peel and slice the potatoes.

Assemble

  1. In a kettle, layer the potatoes with butter, salt, pepper, and sliced onion.

  2. Sprinkle bread crumbs on top.

  3. Pour milk over the mixture and heat until hot.

Bake

  1. Bake at 400°F (200°C) for 2 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, as they cook, release starch that thickens the milk.
Milk
Supplies moisture that cooks down around the potatoes into a creamy sauce.
Butter
Adds fat and richness that carries flavor and keeps the layers tender.
Bread crumbs
Form a topping that dries and browns in the oven for a crisp surface.
Onion
Adds a sharp, savory aroma that mellows during baking.

The step that matters

Bake until the potatoes are fully tender. Potato slices need enough time at heat to soften through, and their starch needs to cook in the milk. Underbaked slices stay firm and the sauce stays thin and starchy.

Swap the onion

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

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

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