Chef's tips
Use cold, plain mashed potato without butter or milk added for the best texture. Do not overwork the dough or the doughnuts will be tough.
Storage
Store in an airtight container at room temperature up to 2 days.
Reheating
Warm briefly in a 300°F oven for a few minutes to refresh.
Common mistakes to avoid
- •Frying at too high a temperature, which browns the outside before the inside cooks.
- •Rolling the dough too thin, which makes the doughnuts dry.
