Jennifer has been involved in food preservation for over 30 years. She learned it from her mom when she was growing up. She has done water bath canning and pressure canning, which are what she has the most experience in. She has also done freeze-drying and has owned two freeze dryers that she had running back-to-back for a couple of years. She first got the freeze dryer for all her chicken eggs but then fell in love with all the things you can do with it, some of her favorites being sour cream, yogurt, grated cheese, cooked beans, and sandwich meat slices. She has done dehydrating, which she cut back on when she got her freeze dryers. However, dried apples with cinnamon are still one of her favorites to dry. She still prefers to do a few things, like greens and herbs, in a dehydrator.
