"yogurt, mint, cucumber, sour cream. shred cucumber, mix some sour cream, mint and yogurt to taste. add salt. let rest."
I'm pretty sure that means:
4 oz plain yogurt (greek would be best)
4 oz sour cream
handful of fresh mint, finely chopped
1/4 t salt
Peel and shred the cucumber. Strain the pulp, then squeeze between paper towels (you want very little added moisture). In a small bowl mix yogurt, sour cream, mint; add cucumber. Taste, add salt, taste, maybe add more salt. Let rest.
