deanlorensen Great gift! So, what I’d do is save that pork fat and use it with your ducks/geese and other birds. I am finding more and more that I prefer pork fat when making sausage from fowl as mixing it with pork butts works but the bird kind of gets run over. Using just pork fat will let the bird stand out more and that is a good thing! Deer can stand up to pork better so I would go ahead and keep doing the pork butt thing with that.
For any sausage like to be in the 70/30 to 80/20 range so I’d just add 2 lb of pork fat to 8 lb of goose. Figure the goose or duck has some fat (depending) already so adding enough to be at 20 should get you in the right area! Enjoy and make sure to share pics. If you like Pepperoni, goose with pork fat is awesome for pepperoni
