Salty, tangy, garlicky, and with a touch of sesame nuttiness, this recipe is all about balance and it's very easy to make. I like to have this salad as a side when I'm serving fish, chicken or even a big cut of meat like beef roast. It's extremely fresh and has a little kick to it to I htink it pairs well with both heavy or lighter mains.
There’s no cooking involved and the dressing has no oil of its own. It’s just black vinegar, garlic, a little sugar, and sesame seeds. The fat and heat come from the chilli crisp spooned over at the end. The oil in chilli crisp carries fat-soluble compounds from the fried chilli, garlic, and Sichuan pepper, and it coats the cucumber differently to a mixed dressing. Once the salad is dressed, serve it straight away.
Why is it called smacked?
Pai huang gua is a Sichuan-style smacked cucumber salad, and the smacking technique is functional, not theatrical. When you hit the cucumber with the flat side of a knife or a rolling pin, you split the cell walls along their natural grain rather than cutting cleanly through them. The result is irregular, jagged edges with far more surface area than a sliced cucumber. More surface area means the salt draws out moisture faster through osmosis, and the dressing clings to the flesh rather than running straight off.
Ingredient Notes
Black vinegar: Chinese black vinegar (Chinkiang or Zhenjiang vinegar) is made from fermented glutinous rice and has a malty, slightly smoky depth that regular rice wine vinegar doesn’t have. It’s less sharp and more rounded. The recipe lists balsamic as an alternative, which is the closest substitute in terms of depth and sweetness, but use a little less because balsamic is thicker and sweeter than black vinegar.
Chilli crisp: Chilli crisp is not the same as chilli oil. A good chilli crisp like Lao Gan Ma contains fried shallots, garlic, and Sichuan pepper mixed into the oil alongside the chilli flakes. The Sichuan pepper brings a numbing, tingly quality that plain chilli oil can’t replicate. Lao Gan Ma is widely available at Asian grocery stores and most supermarkets. Add as much or as little as you like at the end.
Sesame seeds (toasted): Toasting sesame seeds triggers the Maillard reaction on the surface, developing a nutty, roasted flavour that raw seeds don’t have. If your seeds aren’t pre-toasted, a dry pan over medium heat for 2 to 3 minutes until they turn golden is all you need. Shake the pan regularly so they colour evenly and pull them off the heat as soon as they start to smell nutty.
Equipment
- Chopping board
- Chef’s knife or rolling pin
- Large bowl
- Serving bowl
Ingredients
- 1 large cucumber
- 1 tsp salt
- 1 tbsp toasted sesame seeds
- ½ tsp sugar
- ½ tbsp black vinegar (or balsamic vinegar as an alternative)
- 1 clove garlic, finely grated
- chilli crisp, to serve
Directions
Place the cucumber on a sturdy surface. Using the flat side of a large knife or a rolling pin, lightly smack the cucumber five or six times to break it open slightly, but avoid smashing it into mush. Cut the cucumber into 10–12 bite-sized pieces at an angle.
- Put the cucumber pieces in a bowl, sprinkle with salt, and toss to coat evenly. Let the cucumber sit for 10 minutes. After 10 minutes, drain off any liquid that has been released.
- Add the sugar, sesame seeds, black vinegar, and grated garlic to the cucumber pieces. Mix well to combine.
- Transfer the cucumber salad to a serving bowl and garnish with chilli crisp to taste. Serve immediately and enjoy!

Chef Tips
Don’t skip the salting step
The 10 minutes in salt is doing two things at once, seasoning the cucumber from the inside out, and drawing out the excess water through osmosis. If you rush past this and dress the cucumber straight away, that water releases into the dressing and dilutes it. Drain the collected liquid well before adding the dressing, but don’t rinse the cucumber. The residual salt on the surface is part of the seasoning.
Storage
This salad is best eaten straight after dressing. If you want to prep ahead, smack and salt the cucumber up to a few hours in advance, drain, and keep it in the fridge. Add the dressing and chilli crisp just before serving. Once dressed, the cucumber will continue releasing moisture, so leftovers in the fridge will be noticeably waterier the next day.
FAQs
Can I make this ahead of time? You can prep the cucumber up to a few hours in advance. Smack it, salt it, drain it, and keep it in the fridge uncovered. Add the dressing and chilli crisp right before serving. If you dress it and leave it, the cucumber keeps releasing moisture and the dressing loosens and loses its balance.
What can I use instead of black vinegar? Balsamic is the closest substitute in terms of depth and sweetness, and it’s already listed in the recipe as an alternative. Use a touch less than the recipe calls for because balsamic is thicker and sweeter than black vinegar. Rice wine vinegar also works but it’s sharper and more one-dimensional, so the dressing will taste different.
Is this recipe vegan? Yes. All the ingredients are plant-based. Just check the label on your chilli crisp if you’re being strict about it.
