That's hard to answer. That was the only way I knew then and the only way I tried. And it was so long ago. It helped some but probably not a lot.Does just pouring hot water over it help much?
I tried dunking when I got back into chickens when I retired and quit traveling. But it did not take that long for me to switch to skinning. My wife wanted the skin gone. The way I had to heat up water took time and was a fire hazard. I'm much more comfortable skinning now.That would be something I could try, the main reason I do it dry is I don't have any good container for dunking, or a way to keep the water hot.
