Spicy Cucumber Salad

Spicy and light, this one is a tasty barbecue side. There’s an Asian flair to this spicy cucumber salad, provided by the light coating of rice vinegar, sesame oil and soy sauce, and it’s brought to spicy life by a sprinkle of crushed red pepper or cayenne powder. It may look unassuming, but there’s a lot of flavor here. It works as an appetizer or a side, and we love pairing it with savory barbecue. As different as the flavors are, they just work together.

Flavor notes

Why salt the cucumbers first? Salt pulls water out of the sliced cucumbers, and pouring it off before you dress them means the dressing clings to the slices and doesn’t end up as a watery puddle at the bottom of the bowl.

The dressing is small but busy. Rice vinegar brings a mild tang, soy sauce adds salt and savory depth, the sugar rounds off the vinegar, and a teaspoon of sesame oil gives the bowl its toasty aroma. And a full tablespoon of raw garlic makes it sharp, so go lighter if you’re not a garlic fan.

The heat comes in layers: chili paste and crushed red pepper in the dressing, then more chili on top. Crushed red pepper usually runs about 15,000 to 30,000 Scoville heat units, while cayenne runs 30,000 to 50,000, so the two aren’t a one-for-one swap. Using cayenne? Start with about half as much.

Adaptation ideas

Most of these change the heat, and all of them are quick.

  • Want it milder? Skip the sprinkle on top, or use half the crushed red pepper.
  • Want it hotter? Switch to cayenne, add more chili paste, or both.
  • Which cucumbers? English or Persian cucumbers have thin skins and small seeds, so there’s no need to peel them.
  • Add some crunch: Sprinkle toasted sesame seeds or sliced green onion over the top before serving.
  • Too salty? Rinse the salted cucumbers and pat them dry before you add the dressing, since the soy sauce adds salt of its own.

Serving ideas

What goes with it? Anything rich or smoky off the grill.

  • With barbecue: Next to ribs, pulled pork or brisket, where the cool, tangy cucumbers cut the richness.
  • With grilled chicken or fish: As a quick, crisp side.
  • With rice bowls: Spooned on top of rice with grilled meat or tofu.
  • As an appetizer: In small bowls with toothpicks, before the main event.

Storage notes

It’s best the day you make it, while your cucumbers are still crisp. Leftovers keep covered in the fridge, but the slices keep releasing water and get softer by the next day. So drain off any liquid and give them a toss before serving.

Ingredients
  

  • 4 cucumbers
  • 1 tablespoon garlic minced fine
  • 1 tablespoon rice vinegar
  • 1 tablespoon soy sauce
  • 1 teaspoon crushed red pepper or cayenne pepper powder
  • 1 teaspoon chili paste
  • 1 teaspoon sugar
  • 1 teaspoon sesame oil
  • Salt

Instructions
 

  • Slice the cucumbers thin, place them in a bowl, then sprinkle the cucumbers with salt and let them sit for 30 minutes. Water will draw out of the cucumbers. Remove the water from the bowl.
  • Combine the garlic, rice vinegar, soy sauce, chili paste, crushed red pepper (or cayenne powder), sugar, and sesame oil. Pour over the cucumbers and toss the cucumbers to coat.
  • Sprinkle a small amount of either crushed red pepper or cayenne pepper powder on top and serve.

Notes

  • Cayenne is hotter than crushed red pepper, so start with about half as much if you use it instead.
  • Taste a salted cucumber slice before you add the dressing. If it’s too salty, rinse the slices and pat them dry, since the soy sauce adds salt too.
  • Any chili paste works, such as sambal oelek or chili garlic sauce.
