Add Salt and Lemon Juice to Jars

What happens here

Before filling the jars with tomatoes, add one teaspoon of pickling salt and one tablespoon of lemon juice to the bottom of each quart-sized jar. The lemon juice is crucial for increasing the acidity of the tomatoes, which is necessary for safe water bath canning. The pickling salt is for flavor and does not contain iodine, which can discolor canned goods.

Goal: Prepare jars with essential preserving agents.
