I recently bought a few 10″ × 3.625″ × 2.25″ silicone molds from Bramble Berry. What I wonder is if a silicone mold is supposed to be filled all the way to the top, or if I should leave some space. What I like about the numbers 3.625 and 2.25 is that if you divide 3.625 with 2.25 then you get 1.61 which is approximately the golden ratio. I would loose this by filling it to e.g. 2″. I tried to fill a mold to the top, and figured out the amount by oils by using the multiply by .4 trick mentioned in one of the pinned threads. This seemed to fill it to the edge, but I struggle with plastic wrap covering the top of the mold. In the middle of the mold it is touching the batter. Any trick to avoid this?
