Taste a cucumber. It should be salty, but not mouth-puckering. If the veggies are too salty, give them a light rinse under cold water. Transfer salted cucumbers to a medium bowl and fold in dill and vinegar. Transfer to a lidded glass jar and place in the refrigerator to pickle at least another 30 minutes before eating. Pickles will keep in the refrigerator up to 5 days.
