Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the starchy bulk that gives the pudding its body and soft texture.
- Eggs
- Bind the mixture and set it into a firm, sliceable texture when cooked.
- Melted butter
- Adds richness and a smooth, tender mouthfeel to the mixture.
- Flour
- Adds structure, helping the mixture hold together after boiling or baking.
- Milk
- Adds moisture and softness to the second mixture as it sets.
- Moist sugar
- Adds sweetness and moisture, and helps browning during baking.
The step that matters
Tie the mixture in a buttered cloth and boil for 30 minutes. The cloth must be tightly tied and buttered so the pudding releases cleanly and keeps its shape. Boiling must stay gently and steadily going, because a hard or uneven boil can break the mixture apart or make it dense.
