Prepare a boiling water bath canner and keep clean pint jars hot until ready to fill.
Wear disposable gloves while handling the jalapeños. Wash the peppers thoroughly and remove the stems.
Leave small peppers whole and cut 2 to 4 small slits in each one to allow the brine to penetrate. If using larger peppers, slice them into rings or quarter them.
In a large saucepan, combine the white distilled vinegar, water, canning salt, granulated sugar, and garlic cloves. Bring the mixture to a boil, then reduce the heat and simmer for 10 minutes.
Remove and discard the garlic cloves.
Pack the prepared jalapeños tightly into the hot jars, leaving ½-inch headspace.
Ladle the hot pickling brine over the peppers, maintaining ½-inch headspace.
Remove any trapped air bubbles using a non-metallic utensil. Adjust the headspace if necessary, then wipe the jar rims clean.
Apply the lids and screw bands until fingertip tight.
Process the jars in a boiling water bath:
- Pint jars: 10 minutes
- Half-pint jars: 10 minutes
- Adjust processing times according to your altitude if necessary.
Carefully remove the jars and allow them to cool undisturbed for 12 to 24 hours. Verify that each lid has sealed properly before storing in a cool, dark place.

Add a few whole black peppercorns to each jar for extra depth of flavor.
Include a pinch of dried oregano for a subtle Mexican-inspired twist.
Add a few slices of carrot or onion to each jar for additional color and flavor, following a tested recipe if canning.
Mix green and red jalapeños for a colorful presentation.
For a sweeter finish, increase the sugar slightly when preparing refrigerator pickles only. Maintain tested proportions for shelf-stable canned recipes.

Choose firm, unblemished jalapeños for the best texture and flavor.
Always wear gloves when handling hot peppers, and avoid touching your face or eyes.
Leave the recommended ½-inch headspace to help ensure a proper seal during processing.
Use vinegar with 5% acidity for safe home canning.
Allow the jars to rest for at least 2 to 3 weeks before opening so the peppers fully absorb the tangy brine.
Label each jar with the canning date and store in a cool, dark pantry for the best quality.
Once opened, refrigerate the pickled jalapeños and use them within 1 month.
