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.
