Escalloped Onions

Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓

Escalloped Onions

Oven, in the book's wordsA slow oven

Ingredients

Directions

The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the onions

  1. Peel and boil the onions in salted water until tender.

  2. Drain the onions and layer them in a baking dish.

Assemble the dish

  1. Add bits of butter and a sauce made from flour and cream between the layers.

  2. Continue layering until the dish is full.

  3. Sprinkle the top with bread crumbs and bits of butter.

  4. Pour enough milk to nearly cover the onions.

Bake

  1. Bake in a slow oven at 300°F (150°C) for nearly 1 hour.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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

What each ingredient does

Onions
Form the bulk of the dish and turn sweet and soft as they cook.
Flour
Thickens the cream into a sauce that binds the layers together.
Cream
Adds richness and moisture, forming a smooth sauce with the flour.
Butter
Adds fat and flavor and helps the top brown as it bakes.
Bread crumbs
Form a crisp, golden topping over the baked dish.
Milk
Adds liquid that keeps the onions moist as they bake slowly.

The step that matters

Layering with the sauce. The flour and cream sauce must be spread evenly between the layers so it thickens into a binding custard rather than pooling in spots. Covering the onions with milk keeps them moist during the slow bake, so they cook through without drying out.

Swap the onion

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

  1. Potatofits better
  2. Leekfits better
  3. Arrowrootfits about as well
  4. Onionthe original

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