I have a wedding coming up in 2 days. The bride wants SMBC which isn't a problem because it was suppose to be an indoor wedding. Now they have decided to move it outdoors. With the heat I'm afraid that the SMBC will melt. I have talked to her about it but she doesn't want to a buttercream made with shortening at all. Is there a way to make the SMBC more stable? Or does anyone combine SMBC with another type of buttercream?
TIA
