Read the substitution sticky like Burnt said.

If you microwave the QF for 10 seconds it should put it about 100 degrees. I was able to stash it inside (where you can't), so mine stayed a perfect temperature until I needed it. With guys, the temp seems to drop much faster, so you have to be careful! A couple of pair of whitey tighties might help keep it warmer longer.

I would be scared to give a 94 degree sample, but I think they have to accept it, raised eyebrows and all.
