Why it works: Tomato and pepper are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,923 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Scalloped Tomatoes
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Remove contents from the can of tomatoes and drain some of the liquid.
Season the tomatoes with salt, pepper, onion juice, and sugar if desired.
Assemble
Grease a baking dish with butter and cover the bottom with buttered cracker crumbs.
Layer the seasoned tomatoes on top of the crumbs.
Sprinkle the top thickly with more buttered crumbs.
Bake
Bake in a hot oven at 400°F (200°C) until the crumbs are brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the juicy, acidic base that forms the body of the dish.
- Butter cracker crumbs
- Form a crisp, golden topping and base that soaks up some tomato liquid.
- Butter
- Adds richness and helps the crumbs brown in the oven.
The step that matters
Draining the tomatoes. Too much liquid left in the tomatoes will make the dish soggy and keep the crumbs from crisping. Draining some of it lets the topping brown properly and the layers hold together.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, sugar, butter):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, sugar, butter. Candidates are from the same food group and used in at least 100 recipes.
