For crunchy cucumbers that do not make your sandwiches soggy, soaking your cucumbers in salt water will help release some excess water. Then, rinse the salt off and pat them dry for extra crisp slices. First, peel it if you are peeling it. Then, cut them into slices or strips. After, place them in one teaspoon of salt solution to one quart of water and let them sit for two hours in the fridge. Rinse, dry, and make sandwiches!
