Hey folks. I'm new here, hope someone will know this answer. I know that is is wrong to do canning with diary products. My question, is powder milk also not safe to can with. I have a Roasted Red Pepper and Tomato soup that I serve in my cafe and I now also sell by the jar. I jar the soup 1 litre at a time and keep it in the fridge but I'd like to make it shelf stable. Just wondering if I swapped out the 35% cream with dry milk if that would work?
