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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the main body of the dish, cooking down into a tender, starchy base.
- Butter
- Adds richness and flavor, and helps the top brown in the oven.
- Sugar
- Adds sweetness and helps the surface caramelize as it bakes.
- Cream or milk
- Adds moisture and richness, keeping the layers soft as they bake.
The step that matters
Parboil until nearly done. The potatoes must be soft enough to slice and layer but not fully falling apart. Starch in them gelatinizes as it cooks, and overcooking before baking leaves a mushy dish, while undercooking leaves firm, chalky pieces.
Swap the sweet potato
How well each one fits the dish's main ingredients (butter, sugar, cream):
- Potatofits about as well

- Sweet potatothe original
- Chivefits about as well
Fit is the average pairing score against butter, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
