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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

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

  2. Grease a baking dish.

  3. Layer the sliced potatoes in the dish.

Make the sauce

  1. Melt the butter in a saucepan.

  2. Stir in the flour and cook for 1 minute.

  3. Gradually add the cream, stirring until thickened.

  4. Season the sauce with salt and pepper.

Bake

  1. Pour the sauce over the potatoes.

  2. Bake for 45 minutes or until the potatoes are tender and the top is golden.

Butter and flour 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 become tender and soft during baking.
Cream
Adds moisture and richness, and thickens into a smooth sauce with the flour.
Butter
Adds fat and flavour, and helps form the base of the roux.
Flour
Thickens the cream into a sauce by absorbing liquid as it cooks.

The step that matters

Gradually add the cream to the roux. Adding cream slowly while stirring keeps the flour evenly dispersed, so the sauce thickens smoothly without lumps.

Swap the potato

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

  1. Spinachfits about as well
  2. Leekfits about as well
  3. Potatothe original
  4. Chivefits about as well

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