Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sweet potatoes
- Form the soft, starchy base that mashes into the casserole's body.
- Butter or margarine
- Adds fat and richness, smoothing the mashed potatoes.
- Apple cider or juice
- Adds moisture and mild fruity sweetness to the mash.
- Part-skim gruyère cheese
- Melts over the top and browns lightly, adding savory flavor.
The step that matters
Mash until smooth after removing the skins. Potatoes must be fully cooked and soft before mashing; lumps or undercooked starch make the texture grainy, and cooling slightly prevents burns while handling.
