I don't have just one favorite potato recipe.

I think I posted my mother's potato dumpling recipe here. I'll look for it.
I love potato salad. I use lots of hard boiled eggs in mine and homemade relish. I pour pickle juice over the still warm potatoes. They soak up the liquid. Then when you add mayonaise, you don't need as much and the potatoes have a nice flavor and are not dry.
I love mashed potatoes and have tried all kids of different recipes and love each and every one of them. Although I always make the plain old mashed taters.
I grew up with mashed potatoes, a bratwurst and applesauce served up next to the mashed potatoes.
On fridays we had potato boiled in it's skin, mom would peel it and cut it in half, then she would put sour cream on it with chives and we would have pickled herring with lots of the onions, that came with the pickled herring. I still love that one too, but the sour cream we have here in the states is different, than what we had in Germany.
For my mother's homefries, she would use bacon (it came in long chunks, still attached to the skin) she would cut the bacon up real small, no more than 1/4"x 1/4", sautee it to render the fat, then she would sautee chopped up onion until they were just starting to get a lttle brown around the edges. Then she woudl add the cooked chunks of potatoes and fry them until the outsides were crispy. The onions often got
almost burned. This would be served with eggs sometimes. But usually it would be our main meal, seved with mustard.
Now when I make it, I usually add peppers, since I have them either in the garden or the freezer. I will add other stuff too, depending on what I have available: tomatoes, ham, sausage, garlic, green onions, corn, black olives, squash.
I have a few other favorite potatoe recipes. I'll try and remember to look them up for you. As a broke young mother I relied heavily on potatoes for our meals. I just have to find the recipes and I have a lot of my belongings in storage :/
