Dump candy melts in a heat proof bowl. I think candy melts are a little on the thick side so I add in a teaspoon of shortening for each package of candy melts.
Put bowl in the microwave and microwave for 30 seconds. NO LONGER!
Get the bowl out and stir. It won’t look like anything happened and you will be tempted to go longer next time because you find this process tedious. DON’T DO IT!
Put the bowl back in the microwave and microwave for another 30 seconds. Get the bowl out and stir again.
Keep doing this until the chocolate is melted. There will be a point when it is almost melted, just a few little lumps. Try and stir it smooth at this point. I have noticed with the candy melts it is possible to over heat it and then the chocolate gets streaky as it dries.
