Key Ingredients Breakdown
- Persian or Japanese cucumbers: They give you that must-have crunch and mild taste this dish needs. With fewer seeds and thinner skin, they really soak up all the tasty dressing
- Rice vinegar: Brings a soft tartness you just can't get from regular vinegar. Go for the plain type so you can adjust the flavor yourself
- Regular white sugar: Works with the acid to make that famous sweet-sour kick. Don't swap in honey or other sweeteners if you want the real deal
- Fine sea salt: Pulls out extra water, so your salad stays crunchy instead of soggy
Making Your Cucumber Salad
- Getting Ready:
- First, give your cucumbers a good rinse in cool water. Look them over carefully and cut off any bad spots or mushy areas.
- Cutting Method:
- Hold your knife at a tiny angle to the cucumber. Cut super-thin slices, trying to keep them all the same thickness. Mind your fingers and find a steady pace for even results.
- Adding Salt:
- Toss plenty of sea salt over your cucumber pieces. Use your hands to work it in gently, feeling the cucumbers get softer as you go. Let them sit until they release water.
- Making The Mix:
- In another bowl, stir your rice vinegar and sugar until all the sugar melts away. Run your finger through it to check - you shouldn't feel any grains.
- Putting It Together:
- Squeeze the cucumbers firmly to get rid of extra water. Pour your dressing on top and mix everything gently so all pieces get coated.

I grew up in a Japanese home where my grandma made this salad every week. She taught me how important good knife skills and taking your time are for getting just the right texture.
Tasty Food Companions
This cool salad goes great with some grilled salmon or mackerel for a true Japanese dinner. You can also use it between courses to freshen your mouth or make it into a light lunch by adding some cooked shrimp on top.
Fun Twists To Try
Spice up this basic dish by mixing in thin strips of wakame seaweed for an ocean flavor, or throw in some shredded carrots for color and extra crunch. Want more protein? Top it with tofu rolled in sesame seeds or some chilled chicken breast.
Staying Crisp
Keep your cucumber salad in a sealed container in the fridge for up to three days. The cucumbers will get a bit softer but will still taste great. Just drain off any extra liquid before you serve what's left.

After making this dish in my kitchen for years, I've learned that what makes amazing cucumber salad is keeping it simple but paying close attention to each step. This little salad shows that sometimes the easiest dishes can bring the most happiness to your meals.
