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 ↓
Dried Tomatoes
Ingredients
Directions
The book says “a warm oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Pour boiling water over the tomatoes to remove the skins.
Cook the tomatoes until they are half cooked.
Add 1 cup of sugar and 1 tablespoon of salt to the tomatoes.
Dry and store
Spread the tomatoes on plates and dry them in a warm oven at 300°F (150°C).
Layer the dried tomatoes with paper between them.
Serve
When ready to use, stew the tomatoes slowly in plenty of water.
Season with pepper and butter.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Form the main body of the dish, becoming concentrated and chewy as they dry.
- Sugar
- Adds sweetness and helps draw out moisture from the tomatoes.
- Butter
- Adds richness and fat, rounding out the flavor of the stewed tomatoes.
The step that matters
Drying in a warm oven. Tomatoes must dry slowly at a steady low heat so they lose water without scorching. Too much heat can burn the outside while the inside stays wet, spoiling the texture.
Swap the tomato
How well each one fits the dish's main ingredients (sugar, pepper, butter):
- Capsicumfits better
- Potatofits better
- Sweet potatofits better
- Tomatothe original
Fit is the average pairing score against sugar, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
