I do that as well. I have various bags of pork, and chicken bones in the freezer (I dont eat much red meat at all anymore). I use ham bones and pork ribs to make Pork stock which makes the best Split pea soup. And the Chicken and turkey bones make great Chicken soups. Again, I am glad I grew up poor. My kids think eating chicken off the bone is gross.. They would prefer anyting manufactured instead... I dont get it. So absurd..
By the way my Wife bought me a new Electric Smoker cabinet with an Additional Cold smoke attachment. I have an entire king salmon in the freezer (bought from Asian grocery store; only fish affordable in my state) I want to try making smoked Lox. I have made hot smoked salmon before (and we recently had the best hot smoked salmon in seattle last summer) but I have never tried making cold smoked Lox.
Growing up Smoked Makarel was a favorite (served cold, usually eaten with a nice cold beer although when I was young it was Kvass I drank with it). Its definitely a Ukrainian/Russian thing for sure from people I know. There is a place that has some Polish Delis' that sell it but its an hour and a half each way. I need to see if I can find some makarel and make that myself.
