Most "white chocolates" taste closer to butterscotch than chocolate to me. There is no standard of identity set by the FDA for white chocolate, but the process is really different than regular chocolate. Mostly no cocoa solids from the chocolate liquor are used in the process, giving it a distinctly different texture and taste than regular chocolate. Hershey's white kisses kind of have that flavor to me. There are a lot of different methods the kit manufactures could use to try and achieve a white chocolate flavor I suppose.
