I ran across a couple of recipes from the Philippines that add 1/4 tsp saltpeter to fresh sausage recipes.
Both of these then say to leave the mixed sausage meat out at room temperature to stand for an hour before stuffing the casings. I assume this is to allow the nitrate to change into nitrite in the warmth of the room prior to refrigeration or freezing.
Neither of these recipes is for smoked sausage, both go on to stuff then package and then refrigerate or freeze the sausage.
Is this a normal technique?
Does it provide better long term protection against botulism?
Would this be a warm climate technique?
