Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Baked Sweet Potatoes
Ingredients
Directions
The book says “a moderately hot oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Choose sweet potatoes of uniform size and wash them thoroughly.
Remove any imperfect spots and wipe them dry.
Place the potatoes in a 350°F (175°C) oven and bake for about an hour if they are large.
Serve immediately without removing the skins, with cream, butter, milk sauce, or nut butter gravy.
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.
