laketrout, the other thing I would consider putting in the recipe is some electrolyte/vitamin granules (you find them in the horse supply section in small foil envelopes). In reading around on the topic of how sugar syrup feeding compares to honey feeding or nectar feeding, the general thought seems to be that honey and nectar are better food for bees due to their micronutrient profile, although research to clear up just what micronutrients are involved is ongoing.

It may be the placebo effect (irrelevant things that make the beekeeper feel better), but I like adding a small pinch of the electrolyte/vitamin granules.
