Very often, I see tutorials online outlining the method of melting chocolate using a double boiler. That is a perfectly good way to melt chocolate but I find it quite time consuming and a hassle. This is how I melt chocolate for all of my projects, which I have found to be the easiest and quickest. I also melt butter in the same way.
- Put required amount of chocolate into a microwave safe bowl. Microwave for 20 seconds.
- Take it out and give it a good stir. This distributes the heat and prevents the chocolate from burning. Microwave again for 20 seconds.
- Repeat Step 2 until all chocolate is melted. It is now ready for use.
- If using chocolate for piping, pour chocolate into a disposable piping bag with no tip. Snip off the required amount (smaller for fine work, larger for flooding) and use. If chocolate sets, pop entire bag into the microwave for another 10-20 seconds and the chocolate will melt again for immediate use. This saves the hassle of having to remove the hardened chocolate from the bag and having to start from Step 1 all over again.
Hope this was useful!

Not to mention when you (I) accidentally get water into the melted chocolate and ruin EVERYTHING. Haha. 😡
Yes it gets extremely frustrating! Plus all the washing up. The microwave is my best friend I use it for everything from cooking pasta and rice to steaming sweet corn.
