Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Mutton Pie with Potato Crust
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the crust
Boil the potatoes until tender.
Mash the potatoes with milk and butter, then season with pepper and coarse sea salt.
Line a deep dish with the mashed potatoes.
Fill and assemble
Season the cold mutton or lamb with pepper and coarse sea salt, then fill the dish with the meat.
Dot the top with lumps of butter.
Cover with a lid of mashed potatoes.
Bake and serve
Bake in a moderate oven at 350°F (175°C) until the potatoes are golden brown.
Serve in the baking dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the crust and lid, giving a soft interior and a golden, browned top.
- Butter
- Adds richness and moisture to the mashed potato and browns the top surface.
- Milk
- Loosens the mashed potatoes so they spread smoothly and stay moist.
- Cold mutton or lamb
- Forms the savoury meat filling that the potato crust encloses.
The step that matters
Mash the potatoes with milk and butter while they are hot. Potatoes become smooth and spreadable when mashed warm, as their starch is still soft. Cold or overworked potatoes turn gluey or stiff, which makes the crust hard to spread evenly over the filling.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
