Ingredients
4 English cucumbers, sliced into ⅛-inch-thick rounds (about 10 cups)
2 tablespoons kosher salt (such as Diamond Crystal)
1½ cups white vinegar
¼ cup sugar
2 teaspoons fresh ground black pepper
1 small white onion, thinly sliced (about 1½ cups)
Preparation
- Step 1
Toss cucumbers and salt together in a large bowl. Transfer cucumbers to a strainer, then place the strainer in the sink. Let cucumbers sit for 30 minutes as they release their water, stirring occasionally to help them drain.
- Step 2
Meanwhile, whisk the vinegar, sugar and pepper in a large bowl until the sugar dissolves.
- Step 3
Add the drained cucumbers and sliced onion to the bowl of vinegar marinade. Use your hands or tongs to toss well—really get in there and make sure the marinade is distributed. Cover and refrigerate for at least 1 hour before serving, stirring once halfway through to ensure everything gets evenly marinated.

I make a slight variation of this all the time, and it is a huge hit. First, don't drain the cukes! Their liquid has a lot of flavor and will take away some of the vinegar's bite. Also, skip the sugar and use seasoned rice wine vinegar. Finally, be sure to use a sweet onion like Vidalia so the onion does not overpower the other flavors. Let it sit for a few hours, at least, then remove the cukes from the liquid with a slotted spoon before you serve. You can also add shot of flavored oil.
I add sour cream and red onion instead of yellow or white. It’s the way my grandmother made it.
I was intrigued by the recipe's simplicity: I made it for late Sunday brunch, and it was a complete flop - the general consenses it lacked complexity and tasted like pickled fiber. To be completely forthcoming, I served it with olive oil-poached salmon with the Buster Tomato Dressing by Yewande Komolafe (also on this site), so the main course was forward-seasonal.
Would kosher salt such as Morton's be OK?
Used fresh, small white onions from the farmers market and their extra sweet mild flavor was great. I was in a rush to bring this over to a friend's house, so skipped the draining step and served 2 hours after making. The leftovers are pretty watery this morning but last night it was perfect. Brings me back to summers at my grandparents.
Is rice vinegar and rice wine vinegar the same?
