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
Peel and grate the sweet potatoes.
Make the batter
In a bowl, cream the butter and sugar.
Add the eggs and stir well.
Mix in the grated sweet potatoes and sweet milk, stirring briskly.
Bake and serve
Pour the mixture into a baking dish and bake at 350°F (175°C) for one hour.
Serve hot without sauce.

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 starchy body that makes the pudding dense and moist.
- Eggs
- Bind the mixture and help it set firm as it bakes.
- Butter
- Adds richness and fat that softens the texture and carries flavour.
- Sugar
- Sweetens the pudding and helps create light browning on the surface.
- Sweet milk
- Adds liquid that moistens the batter and helps it bake through evenly.
The step that matters
Creaming the butter and sugar. Beating butter with sugar traps air in the fat, which gives the pudding a lighter crumb. Softened butter creams more easily and evenly.
