I remember sausage days when I was a kid. Every year, my aunt, uncle, parents and grandparents would get a couple of hogs fattened and hauled to their favorite butcher to be split in halves. My dad would go get them and the rest of that day and part of the next would be spent making salt cured hams, sausage, souse, rendering lard, making cracklings (the good no-skin kind, not these nearly inedible skin-on things that will about break your teeth). Then we'd stack up concrete blocks to build a temporary smokehouse and hickory smoke the result of our efforts. Half of the sausage went into the deep freeze, the rest hung on wooden poles in the cold room (unused concrete coal bunker under the front porch) after being smoked. Just to walk in there and get a whiff of that smoked meat would get my mouth watering for a plate of sausage, potatoes and sauerkraut. I miss those days when we were all working together. All but my mom have passed on now, so the expertise and experience has passed on with them. We still have the recipes socked away somewhere.
I don't mean to divert the thread, but I wonder if I could prevail upon someone practiced in rendering lard to expound on the correct technique. The intention is to render lard and make cracklings. Some months ago I acquired a quantity of fat back and attempted to render it slow, but the lard was reeking of ash tray half way through and seemed burnt, which I don't understand because I had the stove on low. What did I do wrong? How tricky a process is this? There seems to be more to this than meets the eye.
