Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Macaroni with Tomatoes and Mushrooms
Ingredients
Directions
Add salt and macaroni to boiling water. Boil for 20 minutes, stirring occasionally to prevent sticking.
Drain the macaroni in a colander and rinse with 1 cup of cold water.
Return the macaroni to the pot.
In a separate pan, melt the butter, add the flour, and gradually stir in the stock.
Add the mushrooms, onion, and cayenne pepper. Cook until heated through.
Combine the mushroom mixture with the macaroni, then stir in the parsley and Parmesan cheese.
Serve hot.
