Zucchini Pickles

1. Stage

Combine zucchini and onions in a large bowl; cover with water and stir in salt until dissolved. Let vegetables soak for at least 2 hours, then drain and transfer to a large pot.

2. Stage

Bring sugar, vinegar, mustard seeds, celery seed, turmeric, and yellow mustard to a boil in a saucepan. Pour mixture over zucchini and onions and let stand for at least 2 more hours.

3. Stage

Place the pot with vegetables, spices, and pickling liquid on the stove and bring to a boil. Boil for 3 minutes.

4. Stage

Meanwhile, inspect three 1-quart jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water for at least 5 minutes or until vegetables are ready. Wash new, unused lids and rings in warm soapy water.

5. Stage

Pack vegetables into the hot, sterilized jars, filling the jars to within 1/4 inch of the top with pickling liquid. Run a knife or a thin spatula around the insides of the jars after they have been filled to remove any air bubbles. Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with lids and screw on rings.

6. Stage

Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars into the boiling water using a holder. Leave a 2-inch space between the jars. Pour in more boiling water if necessary to bring the water level to at least 1 inch above the tops of the jars. Bring the water to a rolling boil, cover the pot, and process for 10 minutes.

7. Stage

Remove the jars from the stockpot and let rest, several inches apart, for 24 hours. Press the center of each lid with a finger to ensure the lid does not move up or down. Remove the rings for storage and store in a cool, dark area.
