Fill Jars: Add a small amount (about 1 tsp) lemon juice to the each of the jars then ladle the hot filling into each hot jar, leaving 1/2 inch of headspace. Remove air bubbles, wipe the rim with a damp cloth, and attach the lid and ring. Repeat for remaining jars.
Waterbath Canning: Place jars in a waterbath canner and process for 15 minutes (pints) or 20 minutes (quarts). Adjust processing time for altitude.
Cool Jars: After processing, lift jars straight up from the water and place them on a clean towel. Allow them to sit undisturbed at room temperature for 12 to 24 hours.
Check Seals and Store: Check the seals. Clean the jars, label, and date them. Any unsealed jars should be refrigerated and used within 2 weeks.
