I like to eat duck egg yolk, find the recipe in the kitchen, I tried it myself, and finally got out of oil in a month, very happy!
Very simple, I won't go into details. The duck eggs are cleaned, the white wine is soaked, and the salt is wrapped. I put it in a plastic bag and put it on the mouth. Put it in a ventilated place and you're done.
It’s tempting to look at!
