Why it works: Sweet potato and lemon match in chemistry and in kitchens. They rank in the top 10% of all ingredient pairs, and cooks put them together in 314 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Sweet Potato Pudding
Ingredients
Directions
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
Preheat the oven to 350°F (175°C).
In a bowl, beat the eggs and mix in the softened butter and sugar until well combined.
Add the mashed sweet potato until the mixture thickens.
Stir in the brandy, lemon juice, lemon rind, and spices if desired.
Bake and serve
Pour the mixture into a deep buttered dish.
Bake until set and lightly browned, then let cool.
Serve chilled.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Bind the mixture and set into a firm, sliceable pudding when baked.
- Butter
- Adds richness and a smooth, tender texture to the pudding.
- Sugar
- Sweetens the pudding and contributes to light browning on the surface.
- Sweet potato
- Provides the bulk, moisture and body of the pudding.
- Brandy
- Adds aroma and a warm, boozy flavour that complements the sweet potato.
The step that matters
Bake until set and lightly browned. Egg proteins coagulate as the pudding heats; underbaking leaves it loose and wet, while overbaking makes it dry and rubbery. Look for a firm centre and light colour before cooling.
