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. Cut large onions into quarters.

  2. Boil the onion quarters until tender.

Assemble and bake

  1. Place the boiled onions in a baking dish.

  2. Cover the onions with cream sauce and buttered crumbs.

  3. Bake at 400°F (200°C) until brown.

The flavor team

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.

  1. Cream + saucetop 9% of all pairs

    Shared aroma: ethanol (alcoholic, ethereal).

  2. Onion + creamtop 18% of all pairs

    Shared aroma: ethanol (alcoholic, ethereal).

Onion and cream barely smell alike, yet cooks put them together in 10,827 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

Large onions
Provide the main body of the dish, softening into tender layers when boiled.
Cream sauce
Adds moisture and richness, keeping the onions from drying out in the oven.
Buttered crumbs
Form a crisp, golden topping through browning in the oven.

The step that matters

Bake until brown. Baking long enough lets the buttered crumbs toast and brown on top while the sauce heats through. Pulling the dish too early leaves a pale, soggy topping.

Swap the onion

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

  1. Horseradishfits better
  2. Mustardfits about as well
  3. Spinachfits about as well
  4. Onionthe original

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

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
