Prepare the cucumbers by thoroughly washing and thinly slicing them with a chef's knife on a cutting board. Place the slices into a clean glass jar or container.
2 cups sliced cucumbers
In a mixing bowl, combine the vinegar, salt, dill, sugar (if using), and water. Stir until the salt and sugar are fully dissolved and the mixture is well integrated, forming a tangy brine.
1/2 cup white vinegar, 1 tsp salt, 1 tsp dill, 1 tbsp sugar, 1 cup water
Pour the vinegar brine over the cucumber slices in the jar, ensuring they are fully submerged. Tap the jar gently on the counter to remove any air bubbles and help the liquid penetrate the slices.

Seal the jar tightly with a lid and shake gently to evenly distribute the brine, ensuring all slices are coated. Let it sit at room temperature for about 10 minutes to allow flavors to start blending.
Transfer the jar to the refrigerator and chill for at least 30 minutes before serving. The cucumber slices will develop a glossy appearance and absorb the tangy flavor, becoming crisp and bright.
