I don't even know how to drain the liquid from the grated potatoes. I've tried wrapping the grated potatoes in a dish towel and squeezing, but I'm not convinced that really helps. And I end up with lots of dirty, smelly towels. Can you simply let the liquid drain out in a strainer? Should the extra onion liquid be drained, too? Also, I sort of remember that my Bubbie used to drain the liquid into another bowl, discard the liquid, and put the potato starch (which settled to the bottom of the bowl) back in with the grated potatoes.
What does everyone else do with their grated potatoes? And what kind of oil do you use for frying?
