Does anyone here cook w/Vegan Gourmet cheese? For me, it seems to melt and not melt at the most random times.. For instance, I put it on some chips in the microwave, and it melted in something like 5 seconds. Then, I put it on some mexican pizzas, under the broiler, and it didn't melt at all.. The tortilla practically caught fire and there was no melting of the cheese.. Has anyone else had a similar experience? If so, what did you do?
