Why it works: Butter and romano cheese match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and 130 recipes mention both. Both carry gamma-decalactone, which smells peach, creamy. The science ↓
The recipe
8 servingsIngredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Preheat the oven to 400°F (204°C). Cut the red potatoes into chunks, place them in a pan of boiling water, and simmer about 12 minutes until tender.
Drain the potatoes and mash them with the milk, minced garlic, salt and half the butter. Stir in half the grated Romano cheese until smooth.
In a large skillet over medium heat, cook the ground beef and chopped onion for about 8 minutes, breaking up the meat, until no pink remains and it reaches 160°F (71°C). Drain off excess fat.
Stir the dried rosemary, dried basil, dried oregano, tomato sauce, drained diced tomatoes and drained mixed vegetables into the beef. Simmer over low heat for about 8 minutes.
Spread the beef mixture in a 9x13-inch (23x33 cm) baking dish. Spoon the mashed potatoes over the top and spread evenly.
Sprinkle the remaining Romano cheese over the potatoes and drizzle with the remaining butter, melted. Bake for about 15 minutes until golden and bubbling at the edges, then serve.

Fit is the average pairing score against beef, onion, rosemary, tomato, sauce, potato, butter. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
