Kancha Lanka Piaja
A fiery, rustic Bengali raw salad where sharp onions and punchy green chilies are simply tossed with a squeeze of mustard oil and a pinch of salt. Ready in minutes, this no-cook side delivers an intense burst of heat and pungency that cuts through rich curries and fried dishes, waking up every taste bud.
For 4 servings
- prep · ~2 min
Slice the onion and slit the green chilies.
Peel the onion and slice it very thinly. Slit the green chilies lengthwise, keeping the stems intact if you like for a rustic look.
- mix · ~1 min
Toss everything together with mustard oil and salt.
In a small bowl, combine the sliced onion and slit green chilies. Drizzle with mustard oil and sprinkle the salt over the top. Toss gently with your fingers until everything is lightly coated.
- serve
Serve immediately alongside rice and dal or any fried dish.
Transfer to a small serving bowl. Serve fresh, as the onions will lose their crunch if left to sit too long after salting.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a very sharp knife to slice the onion paper-thin for the best texture and quicker flavor release.
- 2Let the salted onions sit for 1-2 minutes before adding oil to draw out some moisture and mellow the bite.
- 3Slit the green chilies lengthwise but keep the stem on to control heat — remove seeds for a milder version.
- 4For the most authentic pungency, use Bengali kalo sare (black mustard) oil, not a refined substitute.
- 5Serve within 10 minutes of tossing; the onions quickly lose crunch and become limp after salting.
- 6Warm the mustard oil slightly by rubbing it between your palms before adding — it releases more aroma.
Adapt it for your goals.
Milder version
Replace half the green chilies with red bell pepper strips and soak sliced onions in ice water for 10 minutes before draining — ideal for those who want the texture without the intense heat.

Mustard oil is essential for the authentic Bengali character, but you can substitute with a good extra-virgin olive oil or toasted sesame oil for a different but still pungent flavor.
