I hope the latke police will not come after me for saying this, but a latke is basically a tiny fried potato kugel. Assuming you are an average home cook (that would be someone with no access to commercial sized tools/utensils) it might be worth stocking up on muffin trays (or mini muffin trays) and baking little kugels aka latkes. You might have to experiment a little with a recipe to get it more “latke-like”. Most kugels usually freeze well so if its packed properly it shouldn’t be a problem to freeze and reheat. I know some people add water to the mixture which keeps it from turning colors a little longer.
Good luck!
