Of course it's ok! Making traditional potato ones doesn't take a recipe. I just peel and grate some potatoes, add some grated onion, egg, salt and pepper until it is the consistency I want, then form into patties and fry until golden brown on both sides. Sometimes I add some matzah meal, but I often have company over that can't have gluten, so I leave the matzah meal out.
This is the recipe I am planning to use for the cheese latkes:
Cheese Latkes
1/2 cup soft cream cheese (4 ounces)
2 eggs; separated
1/2 cup flour
1 tablespoon sugar
1 cup cottage cheese
1/2 teaspoon salt
pinch of cinnamon, to taste
Mix cream cheese with egg yolks, then add sugar and cottage cheese. Add flour slowly and mix well. Beat egg-whites until stiff, and fold into cheese mixture. Heat oil in pan and drop mixture in by spoonfuls. Fry until brown, and flip. Serve with sour cream or apple sauce. Makes 30 latkes.
