Notes
Recipe Yield and Serving Size: This recipe makes about 1 2/3 to 1 3/4 cups, or 5 servings. Each serving is approximately 1/3 cup.
Storage: Store in a covered glass container in the fridge for up to 3 days. Note that the consistency will thin over time as the cucumbers continue to release their moisture, so give it a quick stir before serving.
