If your pretzel legs are falling off when you're sticking them to the strawberry, make sure the strawberry is completely dry. Hold the pretzels in place for 15-30 seconds to ensure the chocolate has hardened. You should also put the strawberries in the refrigerator to chill before dipping them in the chocolate. If the pretzel legs are falling off while you're dipping the strawberries, it's likely that the chocolate is too hot. Let the chocolate cool before dipping any more strawberries. For the pretzel legs that fall in the chocolate, you can remove them with a spoon or some small tongs and then let them dry on the parchment paper. Stick them to the strawberry with a little melted chocolate once everything has dried and no one will know!
