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).

Assemble

  1. Slice the tomatoes and layer them in a buttered pie dish.

  2. Cover with bread crumbs and season with pepper and salt.

  3. Dot with small pieces of butter.

  4. Repeat layering until the dish is full.

Bake

  1. Bake for 30 minutes.

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

What each ingredient does

Tomatoes
Provide the main bulk and moisture that softens and forms the base of the dish.
Bread crumbs
Form a crisp, golden topping that absorbs juices and browns in the oven.
Butter
Adds richness and helps the topping brown and crisp as it melts.
