I don't whose recipe it was originally but I find it on this site as a response to a group member's request.
- apple cider vinegar
2 tablespoons apple cider vinegar
4 teaspoons sweetener (molasses, maple syrup, honey, sugar)
1/4 teaspoon ground ginger or 1 teaspoon grated fresh ginger
1 cup water
Combine all ingredients in a jar or glass. Cover and refrigerate at least 2 hours and up to a day.
Shake or stir before serving. Taste and adjust sweetener, if desired. If using fresh ginger, strain through a fine sieve or cheesecloth.
Pour over ice or mix with soda water, if desired.
