Combine the water, vinegar, sugar, garlic, and salt into a medium stainless steel or non reactive pot. Heat on high until the sugar and salt are dissolved.
1 ¼ cup water, 1 ¼ cup white distilled vinegar, 3 tablespoon white granulated sugar, 4 - 6 cloves garlic, peeled & sliced in half, 1 tablespoon Kosher salt (regular table salt will cloud the water)
Slice the jalapenos and add to the pot of hot brine. Bring to a boil, and then set the pot aside for 10 minutes.
6 - 8 Fresh Jalapenos, sliced
Ladle the jalapenos and pack into four clean, sanitized 8 oz mason jars.
6 - 8 Fresh Jalapenos, sliced
Pour the hot brine over the jalapenos, to about 1" from top rim of the mason jars.
Place the seals and lids on the jars and tighten moderately. If you are going to Hot Water Bath Process, now is the time to do so.
If not Hot Water Processing, let the jars sit on the counter until they are completely cooled. You should hear four 'pops' as the vacuum created by the cooling jars sucks the seal down.
Make sure lids are not loose, and then refrigerate up to 2 weeks. If you did the Hot Water Bath Canning process, you can store them in your pantry for up to 18 months.
