One handful at a time. Make sure your temperature is right on your scalding water, around 150°F. Plucking geese is a chore. My grandma used to make her own pillows and blankets! Roast your geese on a rack, save all the grease. It's really very versatile. You can make really soft biscuits with goose grease too, or fry veggies in it.I have a LOT of geese... how do you handle the plucking, Bantam?
