Creamed Sweet Potatoes

Oven, in the book's wordsA moderate oven

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

  1. Boil sweet potatoes until soft, then mash and measure 3 cups. Keep the mashed potatoes warm during preparation.

  2. Add salt, paprika, butter, and beaten egg yolks to the potatoes, then mix in the cream.

  3. Beat the mixture until light and creamy.

  4. Transfer to a buttered pudding dish.

Make the meringue and bake

  1. For the meringue, beat egg whites until stiff, then gradually add sugar.

  2. Spread the meringue over the potato mixture.

  3. 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.
