Exactly and that is why some is cured and some is not. To cure them the correct way takes a couple hours of sitting out. I use Pro Cure as I have great luck with it, but it seems to work best is you use half of what it calls for. I have some cured the full way, and some with only the first step of curing. So will have to see how they worked out. I just mixed in the cure, let them sit in the bag, then vacume sealed them. I know I put too much cure in a couple because I could feel the eggs getting a little too solid. Will just have to see how they turn out. The un-cured will be just fine, but i have to cure then the correct way.
