Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Old potatoes
- Starch that breaks down into a soft, fluffy mash when boiled and mashed.
- Butter
- Adds fat and richness, and coats the potatoes for a smooth texture.
- Cream or rich milk
- Adds moisture and fat, loosening the mash and making it smoother and creamier.
The step that matters
Mashing while the potatoes are still hot. Potatoes that cool become stiff and gluey when mashed, and overworking releases starch that makes them gummy. Mash them soft and warm, and add butter while hot so it melts in evenly.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
