Escalloped Potatoes

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Preheat the oven to 350°F (175°C).

Assemble

  1. Layer the sliced potatoes in an earthen baking dish.

  2. Dust the potatoes with flour, salt, and black pepper.

  3. Distribute the butter pieces over the top.

  4. Pour milk into the dish until it just covers the potatoes.

Bake

  1. Bake for 30 minutes until the top is lightly browned and the potatoes are creamy.

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 creamy as they absorb the milk while baking.
All-purpose flour
Thickens the milk into a creamy sauce that clings to the potato slices.
Butter
Adds richness and helps the top brown as it melts over the dish.
Milk
Forms the creamy sauce that cooks the potatoes and thickens with the flour.

The step that matters

Pour milk until it just covers the potatoes. Too much milk makes the dish soupy and too little leaves the top dry. Flour thickens the milk as it heats, so the amount needs to match the potatoes.

Swap the potato

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

  1. Potatothe original
  2. Capsicumfits about as well
  3. Chivefits less well
  4. Shallotfits less well

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