Krembo
According to halacha, when eating a dish of mixed components, one need pronounce only the blessing over the main components, thus for a chocolate croissant one would say the blessing over the dough, and skip the blessing over the chocolate.But in the case of the Krembo, there is no consensus as to which is the "main" component: the biscuit, or the cream and chocolate. One solution is to bless over each component separately.
