Why it works: Parmesan cheese and milk match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and 1,607 recipes mention both. Both carry ethyl 2-methylbutyrate, which smells fruity, apple. The science ↓
The recipe
Ingredients
Contains: egg, milk, wheat (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Boil the macaroni in the milk until quite tender; cut it into half-inch pieces.
Mix the flour with a little stock, and stir into the rest of the stock until it boils.
Strain the macaroni from the milk.
