In my perception, I honestly do not believe in the microwave; it causes radiation to your food. I still prefer the old fashion method of a double boiler. A double boiler is usually used to melt chocolate. You can of cause purchase a double boiler at Amazon whereby there are 2 pots stack on top of each other.
But here, I am gonna show you how to create a double boiler in a home kitchen without a fancy store-bought double boiler.
First off, you will need a heatproof bowl; one that is wide enuff for your pot. I would highly recommend using a metal bowl as it is a good conductor of heat.
Secondly, fill a pot with about 1 to 2 inches of water. You have to make sure that when the water start to simmer, the water will not touch your bowl. This is very crucial because the chocolate or other ingredients will burn instead of melting when the high-temperature water touches your bowl.
Thirdly and lastly, you would wanna use medium-low heat. Place the bowl of chocolate or ingredients on top of the pot and let the simmering water, steam and heat do their magic.
A simple technique and trick to create a double boiler.
