i made latkas and used flour as the binder, no egg. i placed the patties on an oiled a baking sheet and cooked them in the oven at 375F for about 30 mins. when i pulled them out they were quite stuck to the surface (although not burnt).
the latka ingredients (beets and carrots, in this case) had a lot of sugars in them, and i think this may have contributed.
what would help it stick less? cooking for longer time at a lower temperature? sprinkling some flour directly on the baking sheet in addition to the oil? using more oil?
