Escalloped Onions

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. Preheat the oven to 350°F (175°C).

  2. Grease the sides and bottom of a pint tin pan.

Layer and bake

  1. Layer fine rolled crackers in the pan, then add bits of butter, salt, and pepper.

  2. Add a layer of sliced onions, followed by more butter, salt, and pepper, then another layer of crackers.

  3. Repeat the layering process until all ingredients are used, finishing with a layer of crackers on top.

  4. Pour the milk over the mixture, ensuring it rises above the layers.

  5. Bake for 1 hour, adding more milk if necessary.

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

What each ingredient does

White onions
Provide the bulk of the dish and sweet, savory flavor as they soften and cook.
Rolled crackers
Form the crumbly layers that soak up milk and give the dish body and structure.
Butter
Adds fat and richness, helping flavor and browning across the layers.
Milk
Supplies the moisture that softens the crackers and onions as the dish bakes.

The step that matters

Pouring the milk over the layers. The milk must rise above the layers so the crackers and onions absorb enough liquid to cook through and not dry out. Adding more milk during baking, as the record advises, compensates for liquid lost to absorption and evaporation.

Swap the onion

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

  1. Potatofits better
  2. Capsicumfits better
  3. Tomatofits about as well
  4. Onionthe original

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