A dozen duck feet

Two handfuls of salt.

A few slices 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 salt water for at least one day and one night, preferably two days and one night, and then take them out and string them together. I don't know how to string them together. Let's wait until they are soaked.

Dry them in the shade or in the sun until they become hard, and some will prick their hands. Put it in a fresh-keeping bag and keep it in the freezer.
