Wash and dry the jalapenos. Thinly slice them.
Place jalapenos into sterilized mason jars. Add a garlic clove in each bottle.
Bring water, vinegar, sugar and salt to a boil, stirring until sugar and salt dissolves.
Carefully pour the hot brine over the jalapenos until fully submerged. Let it cool to room temperature. Then tightly seal the lid. Refrigerate upto 3 months. Let the pickles sit for 2 to 3 days before using.
Always use sterilized jars to extend shelf life.
