Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 300°F (150°C).
Chop the onion and green pepper very finely.
Peel and slice the tomatoes.
Roll the crackers into crumbs.
Assemble and bake
Place the tomatoes in a baking dish and sprinkle with salt, onion, and green pepper.
Add the rolled cracker crumbs in a single layer on top.
Dot the top with pieces of butter.
Bake for 1 hour.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the main body and moisture that softens and forms the bake's juicy base.
- Crackers
- Rolled into crumbs, they form a topping that absorbs juices and browns in the oven.
- Butter
- Melts over the top, adding fat that promotes browning and rich flavor.
- Onion
- Adds savory aroma and sharpness that mellows as it bakes.
The step that matters
Bake for 1 hour. At a low 300°F, the tomatoes need the full hour to soften and release juices that the cracker crumbs absorb. Pulling it early leaves the base watery and the topping pale.
Swap the tomato
How well each one fits the dish's main ingredients (onion, pepper, butter):
- Potatofits better
- Capsicumfits better

- Tomatothe original
Fit is the average pairing score against onion, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
