Choose a white chocolate with a low viscosity, or that appears very thin when you melt it. Tollhouse’s White Chocolate Chips are one of the better brands for coloring. Go for chips instead of bars, as the smaller the pieces of chocolate are, the faster they will melt. Candy melts are also a good option.
You can buy oil based coloring and powder coloring online. One good brand is Americolor, which creates strong colors without having to add a lot of oil to the chocolate. [1] X Research source If you are trying to create a pale color like light blue or yellow, go for oil based colors as you only have to add very little coloring to the white chocolate to get the color you want. [2] X Research source If you are trying to create a more vibrant color, like a bright yellow or a bold red, buy a powder coloring or paste coloring. The more oil you add to the chocolate, the less smooth it will be. So using a small amount of powder coloring or paste coloring should create a vibrant color without adding too much oil to the chocolate.
Vegetable oil will only make the chocolate more loose and limp, meaning you will end up with messy chocolate covered candies or limp cake pops.
The double boiler method works a bit faster and you have more control over the chocolate as it melts.
You may be tempted to microwave the chocolate for longer than 30 seconds to speed up the process, but don’t do this. Any longer than 30 seconds at a time will heat the chocolate up too fast and cause it to become lumpy.
It’s fine if a few of the chips on the sides of the bowl have not completely melted.
Once the water boils in the pot, turn off the heat. Then, pour the white chocolate chips into the bowl.
You can add a spoonful of vegetable shortening to speed up the process.
Remember that the bowl will be hot, so use a kitchen towel to hold it as you stir!
It’s a good idea to warm your oil up right before you warm up the chocolate, or in between warming up your chocolate. You want to avoid letting the chocolate sit and harden as you warm up the oil.
