Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Form the bulk of the dish, turning tender and starchy as they bake.
- Heavy cream
- Adds richness and moisture, which thickens as it reduces and coats the potato slices.
- Butter
- Adds fat and flavor, helping the potatoes brown lightly on top.
The step that matters
Uncover and bake until potatoes are tender and cream is absorbed. Covering keeps steam in so the potatoes cook through. Uncovering lets the cream reduce and the top brown. Pulling it too early leaves the dish soupy; leaving it too long can dry it out.
