Cocoabliss tip: since this is a ganache recipe, incorporating air with the mixer will reduce the shelf life of the icing. If it’s not a concern, fine. If it is, try mixing with an immersion blender, taking care to burp it as you plunge it into the mix, or simply mix by hand with a spatule or spoon, staying at the centre of the mixture to gradually create an emulsion. This will make a perfectly smooth ganache/icing that can be applied with an offset spatule or piping bag.
