Remove lotus seed stems. If lotus seeds are hard to open, you will have to soften the lotus seeds in water first.
Boil sweet potatoes, lotus seeds and ginseng in salted water until lotus seeds soften and are easily mashable. (should take anywhere 20~30 minutes)
Drain the water and roughly mix or mash everything together to desired texture. I left mine chunky for a bit more of a bite.
Add in seasonings to taste. (I omitted sugar altogether, but this depends on tolerance for Ginseng’s bitterness.)
When the mixture is cool enough to handle, wet your hands and roughly form into patties.
It is recommended to deep fry these in a batter, but I didn’t want to use additional ingredients outside of the pill ingredients (plus I was lazy). So just pan-fry them until golden brown on both sides.
