Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Sweet Potatoes, Southern Style
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 400°F (200°C).
Make the filling
Bake the sweet potatoes until tender, then cut them in half lengthwise and scoop out the insides.
Mash the sweet potato flesh through a ricer.
Add butter and cream to moisten, then season with salt and lemon juice.
Bake and serve
Refill the potato skins with the mixture and bake for an additional 5 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Provide the main body of the filling and the edible skins that hold it.
- Butter
- Adds fat and richness to the mashed flesh for a smoother texture.
- Cream
- Adds moisture so the mashed sweet potato becomes soft and spoonable.
