Fried Mashed Potato Patties Recipe FAQ
They’re sticky due to too much liquid. To make them less sticky add a little bit more flour. Add 1 tablespoon of flour at a time until they’re less sticky.

Yes, you can make the potato patties with freshly made mashed potatoes.
No, baking powder and baking soda are not interchangeable.
