• When possible, preserve fresh, locally-grown summer squash for the best quality and nutritional value. Determine when fresh summer squash are available where you live with this seasonal food guide.

1. Selection

  • Select fresh, tender vegetables that are at peak quality and free of blemishes.
  • Use as soon as possible after harvesting. If the fruits or vegetables cannot be used within one or two hours after harvesting, refrigerate without washing or spread in a cool, well-ventilated place. 

 

Recipes

If this is your first time pickling, or it has been awhile, it is recommended that you read Using Boiling Water CannersGeneral Canning Information and General Pickling Information before beginning. 

2. Ingredients

(Makes 8 to 9 pints)

  • 16 cups fresh zucchini, sliced (3/16-inch thick)
  • 4 cups onion, thinly sliced
  • ½ cup canning and pickling salt
  • 4 cups white vinegar (5% acidity)
  • 2 cups sugar
  • 4 tablespoons mustard seed
  • 2 tablespoons celery seed
  • 2 teaspoons ground turmeric

3. Equipment

  • Water bath canner: Large covered pot (with a tight-fitting cover and a rack) that is deep enough to cover the rack and canning jars by 1 to 2 inches of boiling water. (At least 10 inches deep for pint jars, and 12 inches deep for quart jars.)
  • Canning jars: use standard canning jars without cracks or chips (see recipe for sizes)
  • Lids and bands: bands can be reused if they are in good shape, but lids must be new to ensure a proper seal
  • Long-handled spoon
  • Wide-mouth funnel
  • Jar lifter (for safely moving jars into and out of the canner)
  • Lid wand (for placing lids on jars)
  • Bubble freer, or a plastic or rubber knife-like utensil (for removing air bubbles from jars)
  • Ruler for measuring headspace (Some bubble removers include this feature)
  • Large bowl
  • 4-quart pot
  • Medium pot for extra boiling water
  • 10-quart container or bowl for soaking cucumbers
  • Towels or wire rack for cooling jars
  • Clean white cloth for pickling spices
  • Paper towels
  • Hot pads
  • Cutting board
  • Knives
  • Timer or clock

4. Prepare Canning Equipment

Water Bath Canner-

  • Assemble and wash equipment and containers.
    • Wash canning jars in soapy water, rinse, and keep hot. (This can be done in a dishwasher or by placing jars in the water that is heating in your canner.)
  • Follow manufacturer’s instructions for preparing lids.
  • Place rack in the bottom of a boiling water canner. Fill the canner approximately half full with clean warm water for a canner load of pint jars. For other sizes and numbers of jars, you will need to adjust the amount of water so it will be 1 to 2 inches over the top of the filled jars.
  • Center the canner over the burner and preheat the water to 180 degrees F for hot-packed foods.
  • In medium pot, boil some extra water to use later, as needed, to cover the jars.
  • Begin preparing food for your jars while this water is preheating.

5. Prepare Ingredients

  • Cover sliced zucchini and onions with salt and 1" ice water. Let stand 2 hours. 
  • Drain thoroughly.
  • In 6-quart pot, combine vinegar, salt, sugar, mustard seed, celery seed, and turmeric. Bring to boil. Reduce to simmer.
  • Add zucchini and onions and simmer for 5 minutes.

6. Pack Jars

  • Fill jars with hot vegetables and pickling solution, leaving ½-inch headspace.
  • Remove air bubbles and add more pickling solution, as needed, so headspace is ½-inch.
  • Wipe jar rims with a clean, wet paper towel.
  • Place lid on jar and add screw band. Screw the band down fingertip tight- not too loose nor too tight. Follow lid manufacturer's directions for tightening the jar lids properly.

7. Process Jars

Water Bath Canner-

  • With jar lifter, place jars on canning rack in large pot, which is filled with hot water. Jars should not touch each other.
  • Add or remove boiling water as needed until jars are covered by 1"- 2".
  • Turn heat to high and bring to a vigorous boil. Set timer for correct processing time. Refer to the tables below for processing time for your elevation and jar size.
  • Cover canner with lid and lower heat setting to maintain a gentle boil throughout processing time.
  • When processing time is up, turn off heat and remove canner lid. Wait 5 minutes before removing jars. 
  • Using jar lifter, remove jars and place them on a rack or dry towel.
  • Allow the jars to cool untouched, away from drafts, for 12 to 24 hours before testing lid seals.
  • Once cool, remove the screw bands and check the seal.
  • If any jars did not seal, treat as if 'fresh' and do any of the following:
    • Eat the food immediately.
    • Refrigerate food and use within a week.
    • Freeze.
    • Reprocess. If reprocessing, must repeat the entire canning process.

8. Store

  • Label jars with date and processing information.
  • Store in a cool, dark place, where there is no danger of freezing.
  • For best flavor in pickles, wait five to six weeks before opening.
