Noticed a few of the Blue Potatoes I had were starting to get 'cultured' and realised I had to use up the rest very quickly or I'd have to chuck em all.
So, here's a recipe that the DuSable family has been using for years.

Potato Pancakes

You will need...

4 cups raw grated potato
4 eggs
4 tablespoons grated onion
1/2 cup of milk
4 tablespoons of flour
4 teaspoons of salt and pepper
Shortening (or frying grease of your choice)

Pretty much mix everything except the Shortening in a large bowl, then bring a pan to frying temperature and grease well.
Ladle the mess into the pan in amounts large enough for your desired size of pancake and flip over as each side gains a dark brown.
Repeat until you have nothing left in the bowl and you have a modest pile of warm deliciousness.

Color of Potatoes are optional.
Don't be afraid to experiment a little.
