In a medium sauce pot, combine water through Kosher salt. Bring to a low simmer, stirring until all ingredients (except mustard seed) are dissolved. Remove from heat and allow to cool.
In the bottom of two 16 ounce mason jars, place habanero, garlic and peppercorns, dividing evenly.
Cut cucumbers according to preference, either sliced with a mandolin slicer or into spears. Divide evenly in mason jars.
When cooled, divide liquid into jars. You might have more than you need, that is fine, just discard it.
Screw on tops and place in refrigerator.
The amount of time it will take for them to "pickle" depends a lot on the size of your pickle. Mine were rather thin and cut into 1/2 inch disks, which took 10 days. Thick pickles could take closer to one month.
