干し芋 Drying Sweet Potatoes

さつま芋を大量に買ってしまったので、干し芋作りに挑戦。去年は生の芋をスライスして干して、硬くて食べられませんでした（涙）。干す前に蒸さなくてはいけないってことを知らなかったんですねえ。。。今年は蒸して、再挑戦です！
As I bought a bunch of sweet potatoes, I tried to make dried sweet potatoes. I dried them last year in vain because I didn't know I should team them first before drying. Dried potatoes were so hard that nobody could eat. I tried again this time, surely steamed them first.
