Why it works: Tomato and celery 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 ↓
Tomatoes, with Macaroni
Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Break macaroni into 1-inch lengths.
Stew macaroni in salted water with sliced onion until tender.
Make the sauce
Add tomatoes, pepper, celery salt, and butter.
Thicken with cornstarch.
Serve as a vegetable or transfer to a pudding dish.
Bake and serve
Top with cracker crumbs and grated cheese.
Brown in the oven at 400 °F (200 °C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni
- Forms the bulk of the dish and gives it its body once cooked until tender.
- Tomatoes
- Provide moisture and acidity that form the base of the sauce.
- Cornstarch
- Thickens the tomato liquid into a sauce that clings to the macaroni.
- Grated cheese
- Melts and browns on top in the oven, adding flavor and a golden crust.
- Cracker crumbs
- Add a crisp, browned topping that contrasts with the soft macaroni.
- Butter
- Adds fat and richness to the sauce.
The step that matters
Thicken with cornstarch. Cornstarch must be heated in the liquid to swell and gelatinize; if it is added to cold or insufficiently heated tomatoes it stays grainy and fails to thicken, leaving a thin sauce.
Swap the onion
How well each one fits the dish's main ingredients (tomato, pepper, celery, butter, cheese):
- Capsicumfits better
- Carrotfits better
- Potatofits better
- Onionthe original
Fit is the average pairing score against tomato, pepper, celery, butter, cheese. Candidates are from the same food group and used in at least 100 recipes.
