I have some SMBC in the fridge. Can I bring it to room temperature and add a flavoring to it. I'm thinking of adding a little melted Nutella. I would just whip the two together. Will this work?
Check out jkalman's recipe for an idea about how much of any entity you can add to a batch of SMBC. You'll kind of have to extrapolate it of course, based on how much icing you have in the fridge. I've used hazelnut paste w/IMBC, it's dreammmmmmmmmmmmyyyyy! I just used bittersweet chocolate w/SMBC today and that is awesome too, cuts the sweetness of the icing quite a bit. So many options....!!
