Wash and peel the cucumber. Slice into thin/medium-thin slices. Mix in bowl with vinegar, salt and pepper, and chill in fridge for about 2 hours.
After chilled, drain the cucumbers, and if you don't like the strong vinegar flavor, give them a rinse, too.
Mix in the sour cream. Chop dill and add that in. Mix well and enjoy! This tastes very fresh and cold and is a great accompaniment to anything off the grill, and also goes so well with baked or mashed potato!
