Re: My recipe/method for sugar blocks
My revised 1/3-batch recipe, below, is an improvement, but still coming out a little gooey on the bottom where extra vinegar seems to collect:
19 cups granulated sugar (i.e. 8.3 lbs)
1.3 cups cider
2 tsp citric acid
0.5 tsp Honey-B-Healthy
(I went simple and left out the electrolytes)
Baked at 170F for 8 hours. Allowed to cool overnight.
I did apply cakes made by the above recipe, and in the hives where the cluster was near the top, the bees had covered half the cake before I had the inner cover back in place. They like it! But, it would be easier to work with if it was less sticky and gooey.
For the next batch, I am going to cut the vinegar portion in half. Plus, I may be over-heating it, too, and will revise to 140F for 4 hours.
