Knead the dough in the bowl for about a minute or until it turns into a ball that doesn't stick to the sides of the bowl. If it's too sticky, add more flour; if it's too crumbly, add water, 1 tablespoon at a time until it forms into a ball. Transfer to floured surface and knead until the dough is soft and elastic. Wrap dough in plastic and refrigerate for at least 2 hours.
(To save time, you can can prepare the dough up to this step, and all that's left in the morning is frying the dough.)
