Helpful Tips

Keep the Cucumbers Crisp

Sprinkle cucumber slices with a little salt and let them sit for 15 minutes before preparing the salad. Pat them dry before mixing.

Don’t Over-Marinate

Avoid marinating for more than 24 hours because the vegetables may become soft.

Adjust the Sweetness

Add more sugar for a sweeter dressing or reduce it for a more tangy flavor.

Add Fresh Herbs

Fresh dill, basil, mint, or parsley can enhance the flavor.
