Читать книгу Canning & Preserving For Dummies - Amelia Jeanroy - Страница 47

You have picked your food and washed it carefully. Now, you are in the home stretch, and the way you fill the canning jars is super important:

 Don’t overpack foods. Trying to cram too much food into a jar may result in under-processing because the heat can’t evenly penetrate the food.

 Make sure your jars have the proper headspace. Headspace is the air space between the inside of the lid and the top of the food or liquid in your jar or container (see Figure 3-2). Proper headspace is important to the safety of your preserved food because of the expansion that occurs as your jars are processed or your food freezes.

 Make sure you release the air bubbles from the jar before sealing the lid. No matter how carefully you pack and fill your jars, you’ll always have some hidden bubbles.
