yup, I agree with PinkZiab, IMBC and SMBC will taste the same. They have the same ingredients just different methods for getting the meringue. I love this icing maybe because I love butter. I love butter in my toast, in my cakes, sometimes I cook with it and sweetened butter? even better. I know it's weird but yup I'll take real butter anytime... What I like most to add to IMBC or SMBC is some orange liquer like Grand Marnier... that is my absolute favorite.
