Here’s a new option for freezer jam fans: plastic containers from Ball. The reusable jars are made of heavy-duty plastic and are stain resistant, making them a good choice for tomato sauces, salsas, and soups. The translucent jars come with screw-on lids that lock onto the bottoms of other jars, making them easy to stack. Five 8-ounce jars come in a package for $3 (which includes a packet of freezer jam pectin). While dishwasher safe, they are not heatproof, so you can’t use them for regular canning. You can buy them at CanningPantry.com.
