Why it works: Milk and lemon are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 19,053 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Lemon Meringue Pie
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Preheat the oven to 400°F (200°C).
Place the puff pastry in a pie pan and bake until golden.
Grate the lemons and mix the juice with sugar, cornstarch, and eggs.
Heat the milk in a saucepan until boiling.
Add the lemon mixture to the boiling milk, stirring constantly until thick.
Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.
