Mustard Pickles

1. Stage

Place cucumbers and onions into a large bowl and sprinkle salt over top. Fill the bowl with water until cucumbers are covered. Let stand for 8 to 10 hours.

2. Stage

Drain and rinse cucumbers and onions with fresh water.

3. Stage

Inspect four 1-quart jars for cracks and rings for rust, discarding any defective ones. Immerse in simmering water until needed. Wash new, unused lids and rings in warm soapy water.

4. Stage

Stir sugar and flour together in a 6-quart pot. Whisk in vinegar, turmeric, mustard powder, and celery seed until a smooth paste forms. Add cucumbers and onions and fill with enough water to cover. Stir and bring to a boil. Cook, stirring frequently, until thickened, about 10 minutes.

5. Stage

Transfer cucumbers, onions, and pickling liquid to the hot sterilized jars, filling to within 1/2 inch of the top. Run a clean knife or thin spatula around the insides of the jars to remove any air bubbles. Wipe rims with a moist paper towel to remove any residue. Top with lids and screw rings on tightly.

6. Stage

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.

7. Stage

Remove the jars from the stockpot and let rest, 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.
