Remove the strawberries from the container.
Place them in a bowl of water.
Next, add the vinegar and stir it around.
Set your timer for 2-3 minutes.
Remove the strawberries and place on a cookie sheet lined with paper towels or lint free towels. Cover them and allow to dry completely.
Line the bottom of your jar with a dry paper towel. This will catch any moisture from the strawberries.
Start stacking the strawberries until the jar is full. Screw lid on and place in the fridge.
They should last for 2-4 weeks in the fridge unless you eat them before then haha.
