Waxy Potatoes (Yukon gold, red, etc)
White Vinegar
Bacon
Bacon Fat
Dill
Salt
Pepper
Sugar
Really not a terribly strict recipe. You are basically making a salad dressing (oil, vinegar and seasonings) then pouring them over chunks of baked or boiled potato. Boiled I know works, haven't tried baked though in theory there should be no issues.
So if you want steps,
Cook potatoes
Cook bacon until crispy
Save bacon fat
Crumble bacon and set aside
Mix all the fluids and spices with bacon fat. (except dill) its OK to heat.
Pour over potatoes
Add dill and bacon
Stir and let sit
Eat whenever
