Combine the cottage cheese, milk, and apple cider vinegar in a blender or food processor. Add the dried chives, dried parsley, dried dill, garlic powder, onion powder, salt, black pepper, and sugar. Blend until the dressing is completely smooth and creamy, about 1-2 minutes. I always use Bragg apple cider vinegar because the tang really balances the richness of the cottage cheese, and Good Culture cottage cheese gives the dressing that thicker, creamier texture that makes it coat the peas beautifully.
