Spicy Korean cucumber pickles, called oi muchim, are a typical side dish (banchan) served alongside a Korean barbecue. But they also work quite nicely in a sandwich, alongside grilled meats, or with scrambled eggs. You can even serve them skewered as a garnish for cocktails, like in a martini or bloody Mary.

These cucumber pickles are made by sprinkling crunchy cucumbers with a bit of salt, letting them sit to extract their liquid, and then tossing them with a few seasonings. They're ready within an hour or two, but they will keep for up to a week covered and chilled; just note that the spiciness will increase as it sits.

"The perfect side or topping for any meal lies in well-seasoned pickled cucumbers." —Lauryn Bodden

  2. Chop the Kirby cucumbers into 1/2-inch pieces. If you're using hothouse or English cucumbers, halve them lengthwise and scoop out the seeds, then cut them into about 1/2-inch pieces.

  3. Put the chopped cucumbers in a colander set over a large bowl. Sprinkle the cucumbers with the salt, and toss them gently to combine. Let them sit for 30 to 60 minutes. The salt will draw out water from the cucumbers.

  4. Squeeze the cucumber pieces firmly to release more water; doing this in small handfuls will be the most effective.

  5. Lay the cucumber pieces in a single layer on a clean kitchen towel or paper towels; roll up the towels tightly around the cucumbers to squeeze out even more water.
