Canned Tomatoes with Savory Custard

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. In a bowl, mix the canned tomatoes, grated bread crumbs, and chopped onion.

  3. In another bowl, beat the eggs and combine with milk, salt, and pepper.

  4. Pour the egg mixture over the tomato mixture and stir gently.

Bake

  1. Transfer to a greased baking dish and dot with butter.

  2. Bake for 30-35 minutes until set and golden on top.

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

What each ingredient does

Eggs
Set the custard into a sliceable structure as they cook.
Milk
Adds liquid that cooks with the eggs into a soft, tender custard.
Grated bread crumbs
Absorb liquid and help give the custard body and a light texture.
Canned tomatoes
Provide the main flavor and moisture of the dish.
Butter
Adds richness and helps the top brown lightly in the oven.

The step that matters

Bake until just set. Egg proteins firm as they heat, so overbaking can make the custard grainy, dry, or watery as it weeps liquid. Pull it when the center barely wobbles and the top is golden; it will finish setting as it cools.

Swap the onion

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

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

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