Find melting chocolate over a water bath or microwave a tad messy?
This quick, no mess and no frills way is so very practical but only if you want to use just plain melted chocolate. If you're preparing a ganache or frosting, umm, sorry, some mixing and stirring is required and this method may not be the best.
Just bring a pot of water to a warm temperature ... not boiling. Place the amount of chocolate you need in a heatproof resealable / ziplock / freezer bag. Seal and place bag into pot.
Wait a few moments, hum a tune, feed your cat, and you'll have melted chocolate ready for piping and decorating.
Leave the bag sealed. Just snip off a corner and use it as a piping bag to decorate your favorite dessert. When you're done, toss it in the bin! ... the bag, not the dessert.
