Michelle, The processing time for this pickled dill zucchini canning recipe is specifically for pint jars. I double-checked the recipe in the So Easy to Preserve book, and it states pint jars only. This could be because quart jars weren’t tested or didn’t pass testing.

Canning recipes are tested for safety, including pH levels and heat distribution. So, it’s important to follow the recipe’s listed jar sizes to ensure the best and safest results. Generally, going down a jar size is safe, but not up.

Paige, The jars in the pictures are wide-mouth pint jars and the recipe calls for pint jars. However, you could use half-pints if you want smaller portions. The processing time will be the same.
