Low-Temperature Pasteurization Treatment For Processing
CAUTION: USE ONLY WHEN RECIPE INDICATES
The following treatment results in a better product texture but must be carefully managed to avoid possible spoilage. Place jars in a canner filled half way with warm (120 degrees to 140 degrees Fahrenheit) water. Then, add hot water to a level 1 inch above jars. Heat the water enough to maintain 180 degrees to 185 degrees Fahrenheit water temperature for 30 minutes. Check with a candy or jelly thermometer to be certain that the water temperature is at least 180 degrees Fahrenheit during the entire 30 minutes. Temperatures higher than 185 degrees Fahrenheit may cause unnecessary softening of pickles.
