Pro-Tips for the Crispiest Cucumber Salad

• Mandoline Magic: For the best texture, slice your cucumbers and onions paper-thin. Using a hand-held mandoline slicer ensures uniform slices that absorb the marinade rapidly.
• Salt & Drain for Maximum Crunch: Cucumbers are over 90% water. Toss sliced cucumbers with 1 teaspoon of salt in a colander and let them sit for 15 minutes before adding the vinegar. Squeeze out excess liquid to prevent a watered-down dressing.
• Pickling Liquid Ratio: The classic balanced brine ratio is 1 part vinegar to 1 part water, sweetened with 1 to 2 tablespoons of sugar (or sweetener) and seasoned with salt and pepper.
