Shmaltz is God's gift to mankind. I grew up on the stuff, although most people don't eat it today. I started making it again, because the flavor is so absolutely amazing, and even though it's heart-attack deadly, it is so worth it to have some every now and again. I usually save the chicken fat and skin in the freezer when cooking chickens, and when I have enough, I render the shmaltz. Believe me, there is nothing better than matzoh balls or chopped liver made with shmaltz. My mother fries potato disks in the stuff, one of my best childhood culinary memories.
