4 medium cucumbers, peeled and thinly sliced crosswise
60ml / 1/4cup sour cream
1 tbsp white wine vinegar
1 tbsp olive oil
1 tsp Dijon mustard
1 small red onion, halved and thinly sliced
3g / 1/4 cup chopped fresh dill
Kosher salt
Freshly ground black pepper
Place the cucumbers in a large colander and toss with a couple of large pinches of salt. Set the colander in a large bowl or in the sink and let the cucumbers stand 30 minutes at room temperature to release some of their water.
Meanwhile, whisk the sour cream, vinegar, oil, mustard, a pinch of salt, and a few grinds of pepper together in a large bowl; set aside.
Gently pat the cucumbers dry with a paper towel. Add the cucumbers, red onion, and dill to the dressing and toss gently to combine. Taste and season with salt and pepper as needed.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
