Notes
Seasonings, especially salt, are guidelines. Adjust to taste.
Not a fan of dill? Use cilantro or parsley instead.
I don't recommend distilled white vinegar. It's too acidic.
English cucumbers are elongated cucumbers wrapped in plastic to protect their unwaxed skin. They have fewer seeds than regular cucumbers and are firmer and less watery. If you can't get English cucumbers, regular cucumbers are fine.
You can keep this salad in an airtight container in the fridge for 3-4 days. Remix it before serving. It tastes better the second day after the flavors have had a chance to meld. I don't recommend freezing this salad.
