1 large cucumber
1 tsp coarse sea salt
1 Tbsp light sour cream
1 tsp finely chopped onion
1 tsp fresh dill, chopped
1 tsp vinegar
1/2 tsp sugar
Peel your cucumber - or you can leave the peel on if you want - slice cucumber into fairly thin slices. Place into a colander and sprinkle with coarse sea salt. Set on something to catch the water that drains off, and set aside.
Mix together sour cream, onion, dill, vinegar, and sugar. Cover and place in fridge.
Let cucumbers drain and dressing chill for at least an hour, up to 2 hours.
Before serving, rinse cucumbers under running water briefly. Pat dry with paper towel.
Toss dressing with cucumbers and serve.
