Instructions
prep and ice-brine vegetables:
Wash the cucumbers and peel the onions.
Trim off and discard the stem ends of the cucumbers (they will make your pickles soggy and may taste bitter). Slice the cucumbers into 1/4" slices (use a crinkle cutter if you have one).
Thinly slice the onions into 1/4" slices lengthwise.
Combine the cucumbers and onions in a large mixing bowl, layering with the pickling salt.
Cover the bowl with a layer of ice cubes.
Let the bowl rest for about an hour and a half to draw moisture from the vegetables.
prep jars and canner:
Wash the canning jars with hot, soapy water and rinse well. Place them in your canning pot.
Fill the canning pot with enough water to cover the jars, and begin to bring it up to a boil.
Do not boil standard canning lids (this is outdated advice for modern lid-sealing compounds, unless you are using reusable lids, then follow manufacturer instructions).
make brine and pickles:
In another pot, prepare the pickling marinade: combine the vinegar, sugar, and spices (do not add the Pickle Crisp if you are using it). Bring it up to a boil.
While the brine mixture is heating, rinse the salt and ice from the cucumbers and onions.
Drain the vegetables, then rinse and drain them again.
Add the rinsed cucumbers and onions to the brine pot, and bring it up to a boil again.
fill the jars:
Divide the hot spiced cucumber and onion mixture among the jars.
Top up with the hot pickling marinade, dividing the mixture evenly among the jars.
Leave a 1/2" headspace at the top of the jars. You should have plenty of pickling liquid, but if you need to, you can top the jars up with more vinegar.
If you are using Pickle Crisp, add 1/8 tsp to each jar.
prep jars for canning:
Wipe jar rims with a clean cloth or paper towel dampened with hot water or distilled vinegar.
Top the jars with new canning lids and tighten the bands.
Place the jars in the hot water bath canner and cover with the lid.
water-bath processing:
Bring the water in the canner back up to a boil before starting the processing timer.
Process the jars for 10 minutes at a full boil, then turn off the heat.
When the time is up, leave the jars undisturbed in the canner for up to 5 minutes (this helps prevent siphoning of the liquid from the jars as they cool). Do not leave them longer than this.
cool jars, check seals, & store:
After 5 minutes, carefully use tongs or the jar rack to remove the jars from the water bath.
Place the jars upright on a heat-resistant surface covered with a kitchen towel or wire rack. Do not tighten the lids (*unless you are using reusable lids, then follow manufacturer instructions).
Leave the jars undisturbed for 12-24 hours, then check for seals.
Any jars that did not seal can be reheated and reprocessed with new lids within 24 hours of the initial processing, or refrigerated and used first. I would not recommend reprocessing, as it will make your pickles soft.
Carefully wash jars with warm soapy water if they are sticky, then label them and store them with rings off.
Notes
Altitude Adjustment Chart:
0-1,000 ft – use recipe time
1,001-3,000 ft – increase 5 minutes
3,001-6,000 ft – increase 10 minutes
6,001-8,000 ft – increase 15 minutes
8,001-10,000 ft – increase 20 minutes
Store in a cool, dark pantry. Home canned goods are best consumed within 12-18 months, but should be safe much longer as long as the seal is intact and the jars show no signs of spoilage.
