Mrs. Wheelbarrow's Pickled Green Onions

Prepare the Jars: Inspect four pint-sized jars for any cracks or rust, discarding any imperfect ones. Submerge the jars in simmering water to sterilize until ready to fill. Wash new lids and rings in warm, soapy water (or sterilize in your dishwasher). (5 minutes)

Combine Spices: In a small bowl, mix together the black peppercorns, celery seed, yellow mustard seed, and allspice berries. Divide this aromatic blend evenly among the prepared canning jars. (3 minutes)

Pack the Onions: Firmly pack the green onions vertically into the jars, alternating the direction of the tips (up and down) to maximize space and ensure a tight fit. (15 minutes)

Prepare the Brine: In a saucepan, bring the water, white vinegar, and kosher salt to a rolling boil, stirring until the salt is completely dissolved. (10 minutes)

Fill the Jars: Carefully pour the hot brine into the jars, ensuring you leave a ½-inch headspace at the top. Use a knife or thin spatula to gently dislodge any trapped air bubbles along the inside of the jars. Wipe the rims clean with a damp paper towel to remove any residue. Top with sterilized lids and screw on the rings, tightening until fingertip-tight. (10 minutes)

Process the Jars: Place a rack in the bottom of a large stockpot and fill halfway with water. Bring to a boil and carefully lower the jars (spaced about 2 inches apart) into the boiling water using a jar holder. Add more boiling water, if needed, to ensure the jars are covered by at least 1 inch. Bring the water back to a rolling boil, cover the pot, and process for 15 minutes. (25 minutes)

Cool and Check the Seal: Remove the jars from the stockpot and place them several inches apart on a towel-lined surface. Let them rest undisturbed for 6 to 12 hours. After cooling, press the center of each lid. If the lid doesn't move up or down, the jar is properly sealed. (12 hours)

Store: Store the sealed jars in a cool, dark place, undisturbed, for at least 4 weeks before opening and enjoying. This allows the flavors to fully develop and mellow. (4 weeks)
