I'm a bit confused. I have been wanting to try some silicone molds. But, really how many of these things do you need if you want to make these for sale? I mean, with only a couple of molds, wouldn't it take forever to make enough product to be profitable? If I get a 5 cavity tart mold, how long would I have to wait before I can pop them out of the mold and repour more? For those of you that use molds, how many of the same molds do you have? If I can only make 10-15 tarts (by the time they cool) in an hour, how am I going to make any $$$$$ ! Nancy
