Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Creamed Sweet Potatoes
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the potato base
Boil sweet potatoes until soft, then mash and measure 3 cups. Keep the mashed potatoes warm during preparation.
Add salt, paprika, butter, and beaten egg yolks to the potatoes, then mix in the cream.
Beat the mixture until light and creamy.
Transfer to a buttered pudding dish.
Make the meringue and bake
For the meringue, beat egg whites until stiff, then gradually add sugar.
Spread the meringue over the potato mixture.
Bake in a moderate oven at 350°F (175°C) until the meringue is delicately browned.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the bulk and soft, moist body of the casserole.
- Eggs
- Egg yolks enrich and set the potato base, while whites whip into a stable meringue.
- Butter
- Adds richness and a smooth, tender texture to the potato mixture.
- Cream
- Adds moisture and softness, giving the base a creamy texture.
- Sugar
- Sweetens the meringue and helps stabilise the whipped egg whites.
The step that matters
Beating the egg whites until stiff. Whites must be whipped to firm peaks before sugar is added, since under-whipped foam collapses and the meringue weeps or fails to hold its shape in the oven.
