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 ↓
Baked 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
Wipe the tomatoes and remove a thin slice from the stem end.
Coat and bake
Dip the top of each tomato in the beaten egg, then in the cracker crumbs mixed with sugar, salt, and pepper.
Dot the tomatoes with bits of butter.
Bake in a hot oven at 400°F (200°C) until soft.

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 becomes tender in the oven.
- Beaten egg
- Acts as a binder so the cracker crumb coating sticks to the tomato.
- Cracker crumbs
- Form a crisp, browned topping over the tomatoes as they bake.
- Butter
- Adds richness and helps the topping brown as it melts over the tomatoes.
The step that matters
Coating the tomatoes. The egg must cover the top so the crumbs adhere; otherwise the coating can slide off during baking and the topping will not form a crisp, even layer.
Swap the tomato
How well each one fits the dish's main ingredients (egg, sugar, pepper, butter):
- Capsicumfits better
- Asparagusfits better
- Sweet potatofits better
- Tomatothe original
Fit is the average pairing score against egg, sugar, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
