Scalloped Potatoes

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Peel the potatoes.

  2. Cover the bottom of a baking dish with bread crumbs.

Assemble

  1. Add a layer of sliced potatoes, bits of butter, salt, and pepper.

  2. Fill the dish with alternate layers of potatoes and seasonings.

  3. Wet the whole with milk.

Bake

  1. Bake for 1.5 hours at 350°F (175°C).

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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 soft as they cook.
Milk
Provides liquid that cooks into a creamy sauce around the potato slices.
Butter
Adds fat and richness, helping the top brown during baking.
Bread crumbs
Form a crisp, golden topping and help absorb some of the liquid.

The step that matters

Layering and wetting the dish. Potato slices need even layers and enough milk to cook through. Starch in the potatoes thickens the liquid as it heats, so the dish sets creamy rather than watery or dry.

Swap the potato

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

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

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