Scalloped Potatoes

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

  1. Pare and slice the potatoes very thin.

  2. Soak the slices in water with a little coarse sea salt.

  3. Drain the potatoes and place them in a dish.

Assemble and bake

  1. Add bits of butter, salt, and pepper.

  2. Cover the potatoes with milk.

  3. Bake covered at 400°F (200°C) for 1 hour.

  4. Uncover and brown for 15 minutes.

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, becoming tender as they bake in the milk.
Milk
Becomes a creamy sauce that thickens and coats the potato slices as it cooks.
Butter
Adds richness and helps the top brown during the final uncovered baking.

The step that matters

Uncover and brown for 15 minutes. Baking covered traps steam and softens the potatoes, while removing the cover lets the surface dry and brown. Leaving it covered too long leaves the top pale and wet.

Swap the potato

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

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

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