For this version of Landjaeger, we did actually cook it. It could be made differently, but for our entry level MeatgisticsU course, it’s easier and safer to give instructions on doing a proper thermal processing. (Someday we will have to try to get to doing a completely traditional dry cured version.)
Smoked Meat Stabilizer and Sodium Erythorbate are similar to each other, but definitely not a replacement for a real cure, like Sure Cure. They simply act as cure accelerators, speeding up the conversion of nitrite in sausage during thermal processing. Using an accelerator (like one of these, or Encapsulated Citric Acid) allows you to skip the holding stage after stuffing and go straight into the smokehouse.
