To melt chocolate chips effectively, two common methods are used: the microwave method and the stovetop double boiler method. In the microwave method, place chocolate chips in a microwave-safe bowl and heat on high for 30 seconds. Stir well, then heat again in 15 to 30-second intervals, stirring between each interval until the chocolate is mostly melted. Let it rest a minute or two while stirring occasionally to melt completely and evenly. This method requires careful attention to avoid burning or seizing. The stovetop double boiler method involves filling a pot with about an inch of water and bringing it to a simmer over medium heat. Place a heatproof bowl on top of the pot, making sure the bottom of the bowl doesn't touch the water. Add the chocolate chips to the bowl and stir occasionally until melted smoothly, typically taking 4 to 6 minutes. This method is gentler and better for white chocolate chips. Key tips include using a clean, dry bowl and utensils to prevent seizing, stirring often to ensure even melting, and avoiding overheating to prevent burning or grainy texture. If chocolate seizes, adding a teaspoon of boiling water at a time and whisking vigorously can sometimes restore smoothness.
