I am not a canner but I make soup and stew and such and it is always too much for the two of us. Although we like leftovers we can only eat the same thing so many times. So I had 4 quarts of different leftovers that I put in a 90 minute waterbath. They all sealed perfectly! I was so proud of myself. Next time we came home from out of town doctor’s appointment I just pulled one out and instantly had homemade food! I gave my mom her favorite Thai soup for Christmas too. She couldn’t have been more pleased!
