Sweet and Sour Pickled Fennel

Step 1
Inspect 2 jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until fennel is ready. Wash new, unused lids and rings in warm, soapy water.

Step 2
Place sliced fennel in a colander and rinse well.

Step 3
Combine water, vinegar, and salt in a large saucepan and bring to a boil. Add the fennel, sugar, olive oil, and chives; stir to combine. Bring back to a boil and cook for 3 minutes.

Step 4
Remove fennel from the cooking liquid with a slotted spoon and pack into sterilized jars. Fill the jars with the hot cooking liquid, leaving 1/2-inch head space. Wipe the tops of the jars with a clean cloth. Place lids on the jars and tighten.

Step 5
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 15 minutes.

Step 6
Remove the jars from the stockpot with a jar lifter and let rest on a kitchen towel, several inches apart, for 12 to 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 for 1 week before consuming.
