Why it works: Potato and onion are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Potatoes Baked in Milk
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Preheat the oven to 300°F (150°C).
Cut thin slices of raw potatoes and place them in a baking pan.
Add chopped green onion, season with coarse sea salt and black pepper, and add a piece of butter.
Pour in enough milk to cover the potatoes.
Bake slowly until the milk thickens to the consistency of cream and the top is browned.
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.
