Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Cook the tomato

Cut the tomato into thick slices.
Cook the tomato in a buttered dish in a 350°F (175°C) oven.

Assemble and serve

Trim the poached eggs neatly.
Serve one egg on each slice of tomato.
Sprinkle with parsley and pile the curled bacon high in the center.

What each ingredient does

Eggs: Set when cooked, giving the dish its main body and a rich yolk.

Bacon: Adds savory fat and crisp, browned texture to the top.
Butter: Adds fat and richness, and helps the tomato brown in the dish.
