Zucchini Pickles

Instructions

• Place zucchini and onions into a large bowl and cover with water. Add salt and stir until dissolved. Let vegetables soak for at least 2 hours, then drain and transfer to a large pot.
• Bring sugar, vinegar, mustard seeds, celery seed, turmeric, and yellow mustard to a boil in a saucepan. Pour mixture over drained zucchini and onions; let stand for at least 2 more hours.
• Place the pot with the vegetables, spices, and pickling liquid onto the stove and bring to a boil. Boil for 3 minutes.
• Meanwhile, inspect three quart-sized jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until vegetables are ready. Wash new, unused lids and rings in warm soapy water.
• Pack vegetables into hot, sterilized jars, filling to within 1/4 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe the rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.
• Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and lower jars 2 inches apart into the boiling water using a holder. Pour in more boiling water to cover jars by at least 1 inch. Bring to a rolling boil, cover, and process for 10 minutes.
• 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.
