I made winter patties, the same recipe sold from Dadant. Note: they are not advertised as Pollen Patties but as Winter Patties. I bought them at first thru B & B Honey farms. They priced out at $6 a pattie, not including shipping. I love to make stuff so River found the MegaBee recipe for me on the MegaBee site.
The recipe I use combines my own Honey Bee Healthy, and the MegaBee recipe from the site. The patties come out the consisency of peanut butter.
My bees devoured a pattie a week.
