I love making the Strawberry pastries for my family. I keep the pastries in a ziplock bag, the whip topping mix in the Large Batterbowl in the fridge with the lid on, and the Sliced Strawberrys also in the fridge. When ever we want a pastry it is easy to assemble one or a couple. I think you could also do this at your show if you have more than one demo. Just shortly explain the easy steps you did to make the pastries and whip mix and have the guest use the bread knife and spreader to make their own pastries.
