A dozen duck feet

Two handfuls of salt

Pieces of ginger

2 octagons

Practice of air-drying salted duck feet

Water? Ginger slices? Octagonal? Salt = boiling/cooling

Soak the washed duck feet in cold brine for at least one day and one night, preferably two days and one night, and then take them out and string them with a rope. I don't know how to string them. Let's wait until they are soaked.

Dry them in the shade or the sun until they are hard, and some of them prick their hands. Pack them in fresh-keeping bags and store them in the freezer.
