Why it works: Butter and apple are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 8,706 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Apple Charlotte
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.
Butter a pie dish and cover it with breadcrumbs.
Add a layer of sliced apples and sprinkle with sugar.
Dot with small pieces of butter, then cover with breadcrumbs.
Repeat until the dish is full, finishing with crumbs and butter on top.
Bake at 350°F (175°C) for 45 minutes until brown.
Serve with custard.
