Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Baking apples
- Break down into a pulp that gives the pudding its moisture, body and fruity flavor.
- Potatoes
- Their starch thickens the mixture and gives the pudding a soft, dense texture.
- Eggs
- Bind the mixture and set as they cook, holding the pudding together.
- Sugar
- Adds sweetness and balances the tartness of the apples.
The step that matters
Boil the pudding in the buttered mold for 1.5 hours. Sustained heat is needed for the eggs and potato starch to set the mixture into a firm pudding. The butter keeps the mold from sticking so the pudding can be turned out whole.
Swap the potato
