The Irish Attic credo dictates that you use a rinsed off, but used drinking straw to do this trick but the IA police won’t be at your door if you use an fresh straw.
First wash your strawberries and pluck off the green stem. Then press the straw through the center of the strawberry. If you have trouble with this try starting the straw at the bottom of the strawberry. Just leave the core from each strawberry inside the straw and toss the whole thing when your done.
