Be creative in choosing your ingredients. My senior aunt has dental issues and cannot handle hard pretzels. My son requires gluten-free pretzel crisps. By choosing different candies you can really widen your flavor options!
Cooling takes longer than you might expect, especially if your kitchen is warm. I had so many batches to make, I cheated a little by placing my treats under a fan to speed up cooling.
Remove your items from heat, ASAP, to discourage additional melting. If desired, sprinkle a little sea salt across chocolates. Now, you get to add your candies white the chocolate is still warm.
I highly recommend lining your cookie sheet with parchment paper, whether you use a baking rack or not. Despite your best efforts, there are bound to be drips of melted chocolate.
