10-12 Latkes
3 cups of raw potatoes, shredded and drained
1/2 onion, diced (to taste-- personally, I would use a whole small onion)
1 tsp salt
2 T flour
1/4 tsp baking powder
2 eggs
Drain the potatoes after shredding, in a fine mesh colander, and or by squeezing in a towel.
If the onion is watery, pat it dry.
Mix the flour, salt and baking powder, and toss the onions and potatoes with the flour mix.
Beat the eggs a little, and then mix them with the potatoes.
Drop spoonfuls into enough hot oil to cover about halfway, and flatten with a spatula (the oil to cover halfway means, cover halfway after they are flattened)
Fry fairly hot so they brown reasonably fast (not so fast they burn or are raw in the middle, of course).
Flip when the first side is nicely browned.
Place on papertowels to drain; may keep them hot in a warm oven if cooking a lot of them.
Serve with salt, pepper, sour cream and/or applesauce.
Drying the potatoes is key; twisting them in a dishtowel works well, though it is hard on the towel (discoloring). You can adjust the amount of onion-- we like a fair amount. You can add pepper before frying, though we never do, dunno why. Obviously use oil that takes heat well and does not add flavor-- peanut oil or whatever. Frying fairly hot yields nicely browned latkes, which is what we like, though you might ask your mom what her idea of a perfect latke is, and adjust. I see no reason these won't freeze well (and maybe reheat in the toaster oven); we gobble them up too fast for this ever to occur in our house, however.
(Peeling the potatoes is optional, depending on personal preference, but watch out about putting the peels down your garbage disposal; I have had to pay a plumber twice because potato peels really clog disposals. Maybe next year my husband will agree to make them without peeling, which is how I like them.)
I don't have a great recipe, but have you thought about noodle kugel, seems like good food for someone who is not feeling well.
Best wishes to your mother.
