I started out with 2 cups of water, then brought it to a boil. Slowly stirred in 10lbs of white sugar to a little at a time to prevent scorching. Once all 10 lbs are stirred in with no lumps, I added 1 cup of pollen substitute from my local bee store and make sure to mix it in well. Be mindful, its very powdery and messy if you aren't careful and mix slowly. Once fully mixed in, I emptied the pot into take out containers. The bee store uses 9x9 pans from the dollar store, but also has to spray them before adding the mix. I found that the plastic containers are flexible and allow to break away the brick without having to spray Pam on them beforehand. Just a personal preference though. I let them cool and dry, and after an hour or two, broke them out and sat them directly on top of the frames of my double deep hive. I cut down a 10 frame super to add space to fit the brick, then added my inner cover and top.
I've used sugar bricks in the past, but chose to add some pollen substitute to this batch. I'm hoping to make a couple splits this spring before the honey flow, and the pollen should help with the brooding up. At least that's my hope and theory
