I hope to have some homegrown potatoes waiting for me when I go to Ireland in a couple of weeks...they're so versatile, healthy, and inexpensive.
I hope you enjoy these, I did! These doughnuts keep very well - a characteristic imparted to them by the potato. But, you probably won't need to worry about them being around for long!
One final tip, shake them in powdered sugar only when you're ready to serve them - they keep better unsugared.
