I bought some pork fat earlier this year which i didn't use all of. I kept it frozen straight from the butcher never thawed. I pulled off what i needed and put the rest in the freezer in the same Styrofoam package that i got from the butcher. I'm ready to make some deer sausage however i cant find any pork fat in my area. I remembered that i had some left over from earlier this year. Would this fat still be okay to use to grind up and make deer sausage or do i need to throw this pork fat out?
