Baked Tomatoes

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

Scald, peel, and slice off the stem end of each tomato, leaving about two-thirds of each tomato.
Place the tomatoes cut side down on the buttered bread slices.
Arrange the bread and tomatoes on a buttered baking pan.

Season and bake

Sprinkle each tomato with salt, pepper, and sugar.
Bake in a 350°F (175°C) oven for 30 minutes.

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

What each ingredient does

Tomatoes: Soften and release juices that moisten the bread while baking.
Bread: Forms a buttered base that soaks up tomato juice and browns in the oven.
Sugar: Adds sweetness and helps the tomato surface brown as it bakes.
