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 ↓

Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare

Butter a baking dish.
Assemble and bake
Layer sliced tomatoes in the dish.
Add a layer of thinly sliced onions.
Top with buttered biscuits.
Season with coarse sea salt, black pepper, and a sprinkle of sugar.
Bake until nicely browned.

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 bakes into the dish.
- Buttered biscuits
- Soak up the tomato juices and form a golden, browned topping.
- Onions
- Add savory depth and aroma as they soften under the baking heat.
- Butter
- Greases the dish and adds richness and browning to the biscuits.
- Sugar
- Adds a little sweetness that balances the acidity of the tomatoes and aids browning.
The step that matters
Bake until nicely browned. Baking long enough lets moisture from the tomatoes evaporate and the biscuit topping brown through Maillard reactions. Pulling it too early leaves the layers wet and the top pale.
Swap the tomato
How well each one fits the dish's main ingredients (butter, onion, biscuit, pepper, sugar):

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