Potato pancakes are a very tasty and simple dish. To preserve the potato pancake batter, it is probably better not to put the egg and flour at once. If you grate a lot of potatoes, you can add a little citric acid so that the potatoes do not darken, and put them in the freezer until the next breakfast. Or if you feel like a variety, you can make pancakes. I hope my recommendations will help you. I wish you good luck.
