Scalloped Onions

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Boil the onions until tender.

  2. Separate the onions with a large spoon.

Assemble and bake

  1. In a pudding dish, layer the onions and bread crumbs alternately.

  2. Season with pepper and coarse sea salt.

  3. Moisten the layers with milk.

  4. Bake in a 400°F (200°C) oven until browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Onions
Form the main body of the dish and become soft and sweet as they cook.
Bread crumbs
Absorb moisture and add texture, helping the layers hold together and brown on top.
Milk
Moistens the layers so the bread crumbs soften and the dish stays creamy while baking.

The step that matters

Bake until browned. The oven must brown the top while the layers stay moist. Too little heat leaves the dish pale and wet, while too long can dry the bread crumbs and onions out.

Swap the onion

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

  1. Capsicumfits better
  2. Tomatofits better
  3. Potatofits better
  4. Onionthe original

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