Wash the cucumbers well. Slice into rounds, pickle spears, or your desired shape. Remove ends to prevent softening.
Add garlic cloves, dill sprigs, and optional peppercorns or spices. Then tightly layer cucumber slices into clean jars.
In a small saucepan, combine white vinegar, water, kosher salt, and sugar. Heat over medium heat, stirring until dissolved and hot.
Carefully pour the hot brine over cucumbers, covering them completely. Leave a little space at the top of each jar.
Let the jars sit uncovered until they reach room temperature. Then seal and refrigerate.
Let the pickles chill at least 24 hours. They're even better if you can leave them refrigerated for a week.
