Why it works: Milk and butter 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 ↓
Potato Pudding
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the filling
Boil the potatoes until tender, then peel and mash them to a smooth paste.
Whisk together the milk, eggs, and sugar in a separate bowl to make a custard.
Mix the mashed potatoes into the custard along with the butter.
Bake
Pour the mixture into a pudding dish and bake at 350°F (175°C) until set.
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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the body of the pudding, giving it a thick, smooth, mashed texture.
- Milk
- Adds moisture and liquid to make the custard pourable and creamy.
- Eggs
- Set when heated, giving the pudding its firm, sliceable structure.
- Sugar
- Adds sweetness to the pudding.
- Butter
- Adds fat, enriching the flavour and softening the texture.
The step that matters
Bake until set. The eggs set as they heat, so the pudding must bake until firm in the centre. Overbaking makes the eggs curdle and weep, while underbaking leaves it runny.
Swap the potato
