Temper chocolate quickly and easily using the microwave.
Get all of your ingredients ready and have everything in place to use when needed. Be sure all of your ingredients are at room temperature, including whatever fruit or nuts you will be dipping in or mixing into your tempered chocolate.
Add the 10 oz of vegan chocolate chunks or chips and the shortening to a medium sized glass bowl.
Microwave on 50% power for one minute. Not much will have happened, but stir it with a spatula anyway to spread the shortening over the chocolate. Next, heat for 45 seconds at a time (always at 50% power), stirring after each time, until the chocolate is half way melted (it should take 2-3 times).
Microwave again at 50% power, but now only for 30 second intervals until all the chunks are melted. It should only take one or two times, and be sure to stir before deciding if it needs additional time as the chocolate will not look melted until stirred.
Check the temperature of the melted chocolate. You want it to be between 105 and 107 degrees Fahrenheit (40.5 to 41.6 Celsius). If it is too warm, wait until it cools sufficiently to go to step 6. If it is too cool, heat at 50% power for an additional 15 seconds, stir, and recheck the temperature. Repeat if needed.
Add the 2 oz of vegan mini chocolate chips, and gently stir them in until they are completely melted. You don't need to be too careful here, but you don't want to introduce many air bubbles as they will show on your finished chocolates.
Use your tempered chocolate as desired.
