Why it works: Pepper and tomato 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 ↓
Mexican Macaroni
Ingredients
Directions
Cook the pasta
Break the macaroni or spaghetti into pieces and add to boiling salted water.
Boil for 15 minutes, then add the chopped chili pepper and cook until done.
Make the sauce
In a frying pan, heat the lard and butter.
Add the chopped tomatoes and onions; cook without frying.
If the mixture is not juicy enough, add more butter and a little water.
Once thoroughly cooked, pour the mixture over the macaroni.
Place over low heat and stir until well combined, then serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Macaroni or spaghetti
- Forms the bulk of the dish and absorbs the sauce's flavour and moisture.
- Tomatoes
- Provide moisture and acidity that form the base of the sauce.
- Onions
- Add sweetness and savoury depth as they soften during cooking.
- Butter
- Adds fat and richness, and helps keep the mixture juicy.
- Lard
- Adds fat for cooking the vegetables and carries flavour through the sauce.
- Chili pepper
- Adds heat and aroma to the dish.
The step that matters
Cook the vegetables without frying. Cooking the tomatoes and onions gently lets them soften and release their juices into a sauce rather than browning them. If the mixture dries out, adding butter and water restores moisture so the sauce coats the pasta.
Swap the tomato
How well each one fits the dish's main ingredients (pepper, butter, onion):
- Potatofits better
