Why it works: Onion and mushroom are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 10,626 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Mutton Pie
Ingredients
Directions
Prepare the mutton
Cut the mutton into neat steaks and remove the skin and fat.
Season the steaks with salt, pepper, and minced onion.
If using the loin, divide the kidney and season it as well.
Assemble and bake
Place the steaks in a dish and add stock, port wine, and mushroom catsup.
Cover the dish with puff pastry and bake until golden.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton
- Provides the main meat, which becomes tender during the long baking under the pastry.
- Puff pastry
- Forms a crisp, golden crust that seals in the juices as the pie bakes.
- Stock
- Adds moisture and savoury depth so the meat stays juicy and the filling is not dry.
- Port wine
- Adds sweetness and richness to the sauce, deepening its flavour.
- Mushroom catsup
- Adds concentrated savoury, umami flavour to the filling.
The step that matters
Cover the dish with puff pastry and bake until golden. The pastry must be sealed well around the dish so steam and juices stay in and the meat cooks gently. Baking until golden means the pastry is fully cooked and crisp rather than pale and soggy.
Swap the onion
How well each one fits the dish's main ingredients (mutton, pepper, port wine, mushroom):
- Capsicumfits better
- Shallotfits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against mutton, pepper, port wine, mushroom. Candidates are from the same food group and used in at least 100 recipes.
