Extender Patty recipe: 15-18 TM patties: 6.4 oz(1 packet) TM 25 in 3 lbs sugar (either powdered or granulated) Melt 3 lbs Crisco (barely melt) let cool to point it is a little soupy, pour over sugar/TM mix, and mix thouroughly. Measure out 1/4 to 1/3 pound portions onto wax paper, squash patty flat and let cool (3/8 '' patty). Store patties in airtight container, as TM deteriorates in air. Freezing patties in container works well. from David Lobdell and Steve Wolters, FLA Apiary inspectors. Can also use sugar/crisco (grease) in a 1:1 ratio. Some find granulated sugar keeps the patty around longer: the bees eat it more slowly.
