Tomato Pie

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

Skin and slice the tomatoes.

Assemble the pie

Layer half of the tomatoes in a pie dish.
Add the chops, season with salt and pepper, and cover with the remaining tomatoes.
Mash the butter and milk into a paste and spread it over the top.
Brush the top with a little milk.

Bake

Bake in a 400°F (200°C) oven for about 1 hour and 15 minutes.

What each ingredient does

Tomatoes: Provide the main filling and moisture that softens and sweetens as the pie bakes.
Butter: Adds fat and richness to the paste spread over the top, helping it brown.
Chops: Supply the meat layer that cooks in the juices released by the tomatoes.
Milk: Moistens the butter paste and the top crust, aiding gentle browning.
