Though it may seem like a finicky process, the chocolate will look much nicer and smoother if you don’t over heat it. Follow the directions for microwaving the chocolate just 30 seconds at a time until the chocolate is just melted.
Though you might want to rush the process, refrigerating to speed along the hardening of the chocolate may actually cause it to cool too quickly and mottle, or develop white dots or spots.
For the freshest strawberries possible, serve within 4 hours of dipping. The chocolate-covered strawberries can be stored in the refrigerator for up to 24 hours, but the fruit will start to weep slightly under the chocolate.
