Combine water and vinegar in a small sauce pan over a medium high heat and bring to a boil. Shut off the heat, add salt and allow to cool for 5 minutes.
In the meantime, place dill, garlic, and cucumber slices in a 1 quart jar with a lid.
Once the liquid has cooled, pour it into the jar, pop on the lid and place in the fridge for at least three days. Enjoy!
