Someone told me that it was a good idea to use
PAM ( cooking spray ) as a mold release. This may help
with issues of leaving it in the mold too long.
I tried PAM, and it seemed to me to be beading up, rather than wetting the
silicone surface. I decided not to trust it, and washed it all off, before
using the Vaseline. I'm sure there's some product made for this, and
"only"
$12/bottle...
The RTV silicone (that the molds are made of) is relatively expensive, and
the last thing I wanted to have happen is to find the two halves of the mold
glued together.
