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 ↓
Lemon-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.
Prepare
Boil the lemon peel until tender.
Beat the lemon peel with the sugar until well combined.
Boil the potatoes until tender, then peel them.
Mix
Mix the potatoes, lemon mixture, butter, a little milk, and eggs together until smooth.
Bake and serve
Pour the mixture into a baking dish and bake at 350°F (175°C) until set.
Serve with an acid sauce for best flavor.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and a soft, smooth body to the pudding.
- Lemon peel
- Adds bright citrus aroma and sharp flavor to the pudding.
- Sugar
- Sweetens the pudding and balances the tartness of the lemon.
- Butter
- Adds fat for richness and a tender, moist texture.
- Eggs
- Set as they bake, giving the pudding its structure.
The step that matters
Bake until set. Egg proteins set as they heat, so underbaking leaves the pudding loose while overbaking makes it curdled, rubbery, and weepy.
Swap the potato
