Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Yam Pie
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Peel and slice the yams thinly.
Butter the edges of a large pie dish and line it with pie crust.
Cut the mutton into chops, trim off bones and fat.
Slice the sheep's kidneys and cut the cow-heel into small pieces.
Mix the mutton, kidneys, cow-heel, mushrooms, onion, and seasoning in the pie dish.
Moisten with a small amount of water and cover with a layer of sliced yams.
Cover the pie with a thin layer of paste, moisten and press the edges together, trimming off excess paste and making a hole in the center.
Cover the pie with paper and bake in a 350°F (175°C) oven.
Stew the mutton and cow-heel bones with mushroom and oyster trimmings in 1 pint of water until flavorful, then strain and keep hot.
When the pie is cooked, pour the gravy through the hole at the top and serve hot.
