| Hi Molly - I'm on my 3rd FoodSaver (used them for nearly 20 years now) and all of the models I've had have the wide-mouth jar sealer (my first FoodSaver had both regular and wide-mouth) and will seal Kerr/Ball lids to wide-mouthed canning jars. Models of FoodSavers that don't come with a jar sealer can be purchased separately. The trick to using it successfully (according to manufacturer directions), you need to place the lids in warm water to soften the rubber seal - dry the lids and use. I've used the same lids over and over - just as long as the rubber hasn't gotten brittle and won't seal anymore, reuse is just fine. I keep my large hoard of grains/beans/seeds/grains/pasta in canning jars. Freezer burn is a textural change that happens when moisture evaporates from the surface of a frozen food. When you vacuum seal food you remove all the air and seal the contents in an air-tight bag or a jar. This automatically prevents the moisture from evaporating because it has no where to go. Without vacuum sealing foods, there isn't another type of wrap or bag that will prevent freezer burn. Grainlady |
