Wash and slice your cucumbers. Pack the cucumber slices tightly into one or two clean pint-sized glass jars, leaving about 1 inch of headspace.
Add the garlic, dill, and peppercorns evenly among the jars.
In a medium saucepan, combine the water, vinegar, salt, and sugar. Bring the mixture to a boil over medium-high heat, stirring until the salt and sugar dissolve completely. This takes about 2 minutes.
Carefully pour the hot brine over the cucumbers in the jars, ensuring the cucumbers are fully submerged. Leave about 1/2 inch of headspace at the top.
Let the jars cool on the counter for about 30 minutes. Once cooled slightly, seal the jars with lids.
Place the jars in the refrigerator. Allow the pickles to chill for a minimum of 24 hours before eating for best flavor and texture. They are ready to eat after 24 hours but improve after 3 days.
Notes
For extra crunch, soak the cucumbers in ice water for 30 minutes before slicing and packing.
If you prefer a Kosher Dill flavor, omit the sugar entirely.
These pickles last up to 3 weeks in the refrigerator.
