I'm new here so hopefully I'm posting in the right area. I finally made SMBC successfully (I failed the first two times I ever tried) and so I was very happy about that. I covered it and placed it in the refrigerator intending to use it the next day for cupcakes. When I took it out it was rock solid in the bowl and so I tried mixing it a bit with my spatula. Slowly it started to get workable and I used my hand mixer to get it to working consistency but I noticed it got all gritty and there was liquid coming from it. It was so silky smooth the day before and now it was a mess. I read to try mixing it and as the butter warms it will come together but it didn't. I also read some suggestions to microwave some of the SMBC and mix it in but I don't own a microwave.
I'm so sad! Do any of you guys know what happened and if there's a way to save it? I couldn't bear to throw a third batch out so I put it back in the refrigerator (and it's still separated).
All of your help is much appreciated!
