and cut into 1/3" slices:
Microwave the slices until they're soft (sounds crazy, but it took 10 min. for these):
Bake (raised on a rack) at 200-250' F (95-120' C?) for hours (4 in this case) until they're dry but still flexible (note: they didn't ooze at all):
Cool. (Note that at this point, the 2 end pieces are missing, having been commandeered by the quality control team of Charlie & Gabbie, who pronounced them 'fit for consumption'.)
Feed & repeat:
I don't know if they're as good as Sam's Yams, but they're a whole lot cheaper & Charlie likes them just fine!!
