Scalloped White 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. Slice the potatoes thinly.

  2. Layer half of the potato slices in a baking dish.

  3. Sprinkle a little flour, coarse sea salt, and 2 small lumps of butter over the first layer.

  4. Add the remaining potato slices in another layer and repeat the sprinkling.

  5. Pour 1 pint of milk over all the layers.

Bake

  1. Bake at 350°F (175°C) until well done.

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.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

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 tender layers as they bake.
Flour
Thickens the milk into a creamy sauce that binds the layers.
Butter
Adds richness and fat, helping the top brown and the sauce taste rounded.
Milk
Forms the liquid that cooks the potatoes and turns into a thickened, creamy sauce.

The step that matters

Layering and pouring the milk. Starch from the potatoes and flour thickens the milk as it heats, so the sauce needs even layers and full coverage to set evenly rather than curdle or stay watery.

Swap the potato

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

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

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