I also need advice from an experienced Fowlers preserver. I have done 2 batches of apples and both have leaked water out of the jars, leaving them have full of liquid and with air bubbles. I filled them carefully and tightly, with water level up to the neck of the bottle. They were packed carefully and the rubbers new and lids good. I used 2 clips the first time and only one in the second batch. I watched the temperature and had them at a simmer for one hour. I have an old stove top model. Appreciate any thoughts.
