1 cup apple cider vinegar
½ cup sugar
1½ tsp. kosher salt, plus more to taste
2 English seedless cucumbers
4 shallots, thinly-sliced crosswise
Freshly ground black pepper, to taste
Fresh Mint, cut into thin ribbons for serving, if desired

In a large bowl, whisk together vinegar, sugar, and salt; set aside. Using a vegetable peeler, peel alternate ½-inch-wide strips of skin from cucumbers; discard peeled skins.

Slice cucumber crosswise into 1⁄8-inch-thick rounds; add to bowl with vinegar along with shallots and toss to combine. Season with salt and pepper. Chill, top with mint if using, then serve.
