Why it works: Carrot and turnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,002 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Macaroni and Its Cookery
Ingredients
Directions
Make the sauce base
Make a brown roux by stirring butter and flour over heat until light brown.
Add boiling water, salt, and pepper to the roux.
Make the tomato sauce
For tomato sauce, stew tomatoes and rub through a colander, mixing with white or brown sauce.
For elaborate tomato sauce, simmer tomatoes with carrot, turnip, onion or garlic, bay leaf, peppercorns, cloves, celery, sweet herb, parsley, and roux until tender.
Rub the mixture through a sieve with a potato masher.
If too thick, thin with broth or water and season to taste.
Serve with macaroni
For farmer's dish, boil macaroni and heat with fried onions in oil or drippings.
For Palermo macaroni, boil spaghetti, then simmer with brown and tomato sauce and grated Parmesan for 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Fat that cooks with the flour to form the roux, adding richness and a toasty flavor.
- Flour
- Thickens the sauce as the roux cooks, giving body to the tomato base.
- Tomatoes
- Provide the main body, acidity and flavor of the tomato sauce.
- White or brown sauce
- Adds body and smoothness to the tomato sauce.
- Spaghetti
- Forms the pasta base that the sauce coats.
- Parmesan cheese
- Adds savory, salty flavor and helps the sauce cling to the pasta.
The step that matters
Brown the roux until light brown. Cooking the flour and butter until light brown cooks out raw starch taste and builds nutty flavor, while stirring prevents scorching and lumps that would ruin the sauce's texture.
Swap the tomato
How well each one fits the dish's main ingredients (butter, flour, pepper, sauce, carrot, turnip, onion):
- Leekfits better
- Parsnipfits better
- Shallotfits better
- Tomatothe original
Fit is the average pairing score against butter, flour, pepper, sauce, carrot, turnip, onion. Candidates are from the same food group and used in at least 100 recipes.
