I am using a Baltic Birch 18 bar slab mold (fairly new at trying this mold out) with the dividers and I have noticed on my last 2-3 batches that I am not getting a full gel........all the way out to all sides? I let it gel on my Hoosier Cupboard with lid on and double layer towels on the bottom for it to sit on, and 3 towels over it tucked in on all sides. The last 2 batches had honey in them and that should of heated everything up but it still didn't gel clear out to the edges. What am I doing wrong?? Maybe I should set it in a warm oven.....not turned on..just turn it on long enough to heat up a bit then shut it off and set my mold in there? My outside edge bars look dorky with the half gel effect going on..... Thanks for any input!
