In a medium saucepan combine water, vinegar, garlic, salt and sugar. Bring to a boil whisking until sugar and salt are dissolved. Remove from heat, let cool 15 minutes.
Slice jalapenos and add them to the jars ( I use 3-4 pint jars) . Add the pickling juices to the jars, make sure you get some garlic cloves into each jar. Let cool to room temperature then add lid and place in fridge.
