Hello all, I just purchased a couple of Pavoflex ramp silicone molds but I'm having trouble unmolding the dessert I'm making with them. I've piped chocolate mousse into the cavities and frozen them for 2+ days in my walk-in freezer. When I pop the bars out of the mold, they don't unmold cleanly and I'm losing the nice detail. It *might* be the sugar content of my mousse but it's not particularly sweet. Would adding gelatin to the mousse help? Should I pan spray/cocoa powder dust the molds before piping in the mousse? Any tips/tricks/advice would be much appreciated! Thank you!
