Why it works: Rice and pepper are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 8,379 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Mutton Pie

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.

Preheat the oven to 350°F (175°C).
Layer the sliced cold roast mutton in a buttered baking dish.
Add the cold gravy and currant jelly, then dredge with a little flour.
Cover with paste or a crust of cold rice or mashed potato.
If there isn't enough gravy, add a little water.
Season with pepper, coarse sea salt, and add a piece of butter on top.
Bake for 45 minutes.
