Method
Prepare vegetables
- Wash cucumbers and onions and trim cucumber blossom ends. Slice cucumbers 1/8–1/4 inch thick and slice onions thinly. Keep vegetables chilled until ready to use.
Make brine
- In a large pot combine sugar, vinegar, kosher salt, mustard seeds, pickling spice, crushed red pepper (if using), and 1/2 cup water. Bring to a boil, stirring until sugar and salt dissolve, then reduce to a simmer.
Quick blanch and pack
- Working in batches, add cucumber slices to simmering brine for 60 seconds, then remove with a slotted spoon and drain briefly. Tightly pack cucumbers and onions into sterilized jars, leaving 1/2 inch headspace.
- Pour the hot brine over packed jars, maintaining 1/2 inch headspace. Remove air bubbles, wipe rims clean, apply lids and screw bands finger-tight.
Process or chill
- For shelf-stable jars: place jars in a water-bath canner, cover with water by 1–2 inches, bring to a rolling boil, and process half-pint jars for 10 minutes. Remove and cool undisturbed. For refrigerator pickles: let jars cool to room temperature, then refrigerate; wait at least 3 days before eating.
Finishing
- After jars cool, check lids for seals (center should be concave). Label with date. Store canned jars in a cool dark place up to 12 months and opened or fridge jars for 6–8 weeks.
Notes
Trim blossom ends of the cucumbers to avoid softening. Use 5% vinegar for safe acidity when canning and maintain the 1/2-inch headspace. For a quicker fridge-only batch, skip the water-bath and refrigerate; flavor improves after 3 days.
