I’ve written about making and feeding my bees sugar cakes before. I think I stole this idea from Honey Bee Suite, like I do many things, though I don’t do anything exactly the way anyone else does it. The basic recipe is 12 parts sugar mixed with 1 part water.
There’s a formula for mixing it more precisely depending on sea level and atmospheric pressure, but I don’t worry about any of that. If it’s too wet, I add more sugar or just give the cakes (or bricks) more time to dry. The only thing I do that might be considered innovative is add honey to the water to make the sugar more attractive to the bees, the logic being that if the sugar smells like food (honey), the bees will be less likely to toss it out the front door like they often do with dirt and debris. That’s my big secret to making sugar cakes: make it smell like honey. Or drop in a bit of anise or lemon grass oil, something to attract to the bees to the sugar. Mind. Blown. I know.
