They are ideal for preserving salsas, syrups, sauces, fruits, vegetables and so much more. The absence of shoulders in each 8-oz mason jar makes it suitable for hot-fill canning, water bath canning, pressure canning and freezing. It also ensures that no oxygen gets into the jar after processing and that your food will remain preserved just the way you created it. Once it's sealed, you can store food items in the refrigerator for up to 3 weeks or in a cool place for 1 year. For your convenience, canning instructions are included on the box of these wide mouth mason jars.
