Method
- Toast sesame seeds in a dry pan over medium-low heat for 4 minutes until they pop and turn pale gold. Cool. Grind to a coarse paste in a mortar — the oils should release; the texture should be slightly oily, not powdery.
- Heat mustard oil in a small pan until just smoking — destroys raw pungency. Add fenugreek seeds and let them turn dark brown (10 seconds).
- Pour the hot infused oil immediately over the boiled potato cubes in a wide bowl. The flash-heat releases flavours.
- Add ground sesame paste, ground timur, slit chilies, matchstick ginger, minced garlic, turmeric, lemon juice, salt and sliced onion. Toss thoroughly with hands (or a spoon) for 60 seconds — the potatoes should be coated in the sesame-mustard dressing.
- Taste — should be sharply sour, salty, with the timur tingle and the sesame's warm bottom note. Adjust salt or lemon.
- Stir in cilantro. Add boiled peas or chickpeas if using. Serve at room temperature as a side at a dal-bhat plate. Aloo achar keeps 3 days refrigerated; the flavours intensify.
Common questions
Can Aloo Achar be made ahead?

Is Aloo Achar spicy?
Aloo Achar as written is mild to mildly warming — the heat comes from aromatics rather than chili. Add fresh sliced chili or chili oil at the end if you'd like to push it spicier.
Is Aloo Achar vegetarian or gluten-free?
Aloo Achar is suitable for vegetarian (and vegan if dairy is omitted) diets.
How hard is Aloo Achar to make at home?
Aloo Achar is approachable for a home cook with basic stove skills — total time about 35 minutes, no special technique required.
Can Aloo Achar be scaled up or down?
This recipe is written for 4 servings. To scale, multiply each ingredient proportionally; the cooking times stay the same up to about double the volume. Beyond that, expect to cook in batches because of pan size and heat distribution.
Cultural Note
Aloo achar is the Nepali potato pickle that's eaten as a side, snack, or substantial appetizer. The dish appears at festival plates (Dasain, Tihar), at samay baji (Newari ceremonial feast), and at every dal-bhat thali. The toasted sesame paste is the Nepali signature ingredient — without it, the dish is just spiced boiled potatoes, but with it, the dish reaches its full character. Modern variations include green pea and chickpea additions. The mustard-oil-and-fenugreek tempering technique is shared with many other Nepali dishes; it gives the cuisine its distinctive note.
