I canned my first 1/2 bushel of Romas last week. I blanched then put in sterile Qt. jars. Added a teaspoon of salt and water bathed them for 10 Min. Went to do another batch last night and while re reading the directions it talked about cold canning to water bath for 45 Min..... I did the second batch for 45 min. ??? Whats with the time difference? Both sealed great. Do I need to be concerned about my first batch?? THANKS!!!
