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 ↓
Tomato Macaroni
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Break macaroni into pieces about 3 inches long and boil until tender.
Assemble
Butter a deep dish and layer sliced tomatoes on the bottom.
Add a layer of stewed macaroni and season with salt, pepper, and bits of butter.
Continue layering with tomatoes and macaroni until the dish is full.
Top with a layer of cracker crumbs and bits of butter.
Bake
Bake at 400°F (200°C) for about 30 minutes or until well browned.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the starchy body of the dish, setting into tender layers as it cooks.
- Tomatoes
- Provide moisture and acidity that keep the layers juicy and flavourful as they bake.
- Butter
- Adds fat and richness, helping the top crumbs brown in the oven.
- Cracker crumbs
- Form a crisp topping that browns during baking.
The step that matters
Layering until the dish is full. Packing the layers evenly keeps the dish from baking unevenly, so the centre cooks through while the top browns.
Swap the tomato
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits about as well
- Tomatothe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
