Do you render your own lard or do you purchase it already rendered? There is where I'm lazy. There is a huge hispanic population where I live, so I buy it at a market that caters to them. Just stuffed my thuringer, not 10 minutes ago. Used some collagen casing for part of the batch. Wow. Nice stuff to use. So easy to put on the extruding cone, so uniform. Looking forward to seeing how it smokes out.
