Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure. The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat the oven to 400°F (200°C).

Layer and bake

  1. In a baking dish, layer the chopped meat.

  2. Add the celery, onion, parsley, thyme, salt, and pepper on top.

  3. Cover with a layer of tomatoes.

  4. Add a layer of toasted bread crumbs.

  5. Repeat the layers until the dish is full, finishing with bread crumbs on top.

  6. Dot the top with small lumps of butter.

  7. Bake for 25-30 minutes until heated through and golden.

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

What each ingredient does

Cold meat
Forms the bulk of the dish and provides its savory, meaty base.
Tomatoes
Add moisture and acidity that keep the layers juicy as they bake.
Toasted bread crumbs
Add structure to the layers and absorb juices while browning on top.
Butter
Adds fat and richness and helps the top brown golden in the oven.
Onion
Adds aromatic sweetness and savory depth as it softens in the bake.

The step that matters

Layering the bread crumbs and tomatoes. Repeating the layers evenly keeps moisture distributed so the crumbs do not dry out or turn soggy in patches. Finishing with crumbs and butter lets the top brown properly in the oven.
