Why it works: Celery and tomato are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,377 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Macaroni with Tomatoes
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 the macaroni
Cook macaroni in boiling salted water until very tender.
Transfer macaroni to very cold water to remove starch.
Make the sauce
Heat butter in a pan.
Cook chopped onions until slightly yellow.
Add green pepper, celery, salt, pepper, sugar, and baking soda to the onions.
Cook the strained tomatoes.
Add tomatoes to the onion mixture and thicken slightly if necessary.
Assemble and bake
Butter a dish.
Layer half of the macaroni.
Pour half of the sauce over it.
Add the remaining macaroni and sauce.
Dot the top with butter.
Cover with breadcrumbs mixed with melted butter.
Bake at 400°F (200°C) for 20 minutes, or if prepared in the morning, bake for about 30 minutes before serving.

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, holding its shape in layers as it bakes.
- Onions
- Provide sweetness and savory depth as they soften and turn slightly yellow.
- Strained tomatoes
- Supply the liquid and acidity that form the sauce coating the macaroni.
- Butter
- Adds richness and fat, and browns the crumb topping in the oven.
- Bread crumbs
- Form a crisp, golden topping when mixed with melted butter and baked.
The step that matters
Transfer macaroni to very cold water. Chilling the cooked pasta stops residual cooking and rinses away surface starch, so the noodles stay separate and do not turn gummy when layered and baked.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper, celery, tomato, sugar, bread):
- Capsicumfits better
- Carrotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against butter, pepper, celery, tomato, sugar, bread. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
