Chocolate purists like Mrs. Pastry will protest the presence of this substance in the chocolate section as it really isn’t a chocolate at all. The only reason it’s called “white chocolate” is because it contains cocoa butter — and you can tell if the white chocolate is reasonably high quality as it delivers that inimitable unctuous cocoa butter mouthfeel. White chocolate is among the sweetest of the chocolate confections at 55% sugar (though that’s a maximum by law in America). The rest is made up of cocoa butter (up to 30%), milk solids (15%) plus lecithin as an emulsifier. Lower quality white chocolates make use of cocoa butter equivalents (CBE’s) like palm oil, and as with low quality milk chocolates you can really taste the difference.
