My secret to keeping strawberries, blueberries, and blackberries fresh and mold free.
In a large bowl (I use a salad spinner) or sink, add 3 cups of water to 1/4 cup of white vinegar or apple cider vinegar. Let the berries (strawberries, blueberries, or blackberries) soak for about 5-10 minutes in the vinegar bath. Remove the berries, rinse with freshwater, and dry on a towel on the counter. Once dry, store the berries in a paper towel-lined container with a lid.
