I'm looking for a caramel recipe that can be used as a filling for a wedding cake. I've tried a whipped caramel filling, but I'm hoping to find something more like a thick salted caramel sauce. Ideally it will not be so runny that it oozes everywhere, but not so solid that the cake is hard to cut (the cake will be stored in the fridge and served at room temperature). Does anyone know of a caramel that fits the bill? Thanks in advance!
