Khokana Roasted Mustard Oil: Nepal's Signature Oil

Khokana is a small Newari town just south of Kathmandu, and for generations it has been Nepal's centre for pressing mustard seed into oil. The name stuck the way "Champagne" or "Darjeeling" sticks: say Khokana to a Nepali cook and they know exactly what you mean, a dark amber oil with a peppery, almost horseradish-like bite that mellows into a warm nuttiness once it hits a hot pan.

Our Khokana Roasted Mustard Oil from DRUKCAN is roasted before pressing, which is what gives it that deeper, toastier edge compared to a plain cold-pressed oil. It is the single most requested item in our cooking oils aisle from customers who grew up on real Nepali achar and could never find it quite right with anything from a regular Canadian grocery aisle.

If you are new to Nepali and Indian pantries altogether, our Nepali & Indian grocery delivery across Canada hub is a good starting point before you dive into mustard oil specifically.

We carry two mustard oils and the difference matters more than the label suggests. The roasted Khokana Mustard Oil is toasted first, giving it a rounder, slightly sweeter pungency that Nepali households lean on for achar and everyday tarkari (vegetable curry).

Our Pure Mustard Oil is the straight cold-pressed version, sharper and more assertive, closer to what you would find labeled "kachi ghani" in an Indian kitchen. It is the one to reach for when a recipe wants that raw, nose-clearing heat, like a quick fish fry or a Bengali-style mustard oil drizzle at the end of cooking.

If you cook across both Nepali and Indian traditions and want the full breakdown of how mustard oil stacks up against sunflower and canola, we wrote a whole comparison in Mustard vs Sunflower vs Canola Oil for Nepali Cooking.

The classic move is heating the oil until it just starts to shimmer and lightly smoke, which cooks off the raw sharpness before you add your tadka (tempering) of cumin, mustard seed, or dried chili. Skipping this step is the number one reason people find mustard oil "too strong": raw, it is punchy; heated properly, it turns rich and savoury.

For that tempering step, keep a jar of black mustard seeds on hand. They pop and release a nutty aroma the second they hit hot oil, and pairing mustard seed with mustard oil is a very deliberate, very Nepali double-down on flavour, not a coincidence.

It also shows up constantly across our spices & masala shelf as an ingredient other blends are built around, and if you are still assembling a broader Nepali or Indian spice kit, our guide to garam masala and everyday Indian spices is a solid companion piece.

Ask any Nepali home cook why mustard oil never runs out in their kitchen and the answer is usually achar, not curry. Mustard oil is the traditional preserving medium for Nepali pickles because its natural pungency and antimicrobial quality help keep vegetables, lemons, and fruit shelf-stable for months without refrigeration.

You can see this in action in our pickles (achar) selection: our Mango Pickle and Mixed Pickle are both built on a mustard oil base, which is exactly why they taste sharper and more alive than a vinegar-based Western pickle.

If you want to make your own batch at home with fresh vegetables and a splash of roasted mustard oil, our Indian & Nepali Pickles (Achar): Mango, Lemon, Mixed guide walks through ratios and technique, and Nepali Achar Types Compared helps you decide which style to start with.

Mustard oil has a high smoke point, well above most vegetable oils, which makes it forgiving for pan-frying, sekuwa-style grilling, and deep frying pakauda without breaking down or turning bitter. Store it in a cool, dark cupboard rather than next to the stove; heat and light are what dull its flavour over time, not age itself.

A well-sealed bottle keeps for a long time, so it is worth ordering the larger size if mustard oil is already a staple in your cooking rather than an occasional ingredient. We have customers across the country who order two bottles at a time precisely because reordering shipping takes a few days.

For the health side of the conversation, particularly around erucic acid and why mustard oil is sold for culinary use in Canada, we cover it directly in Mustard Oil Health Facts: What to Know.

Most Canadian pantries default to a neutral oil like our Sunflower Oil for everyday cooking, and there is nothing wrong with that for pancakes or scrambled eggs. But swap it in for a Nepali dal or an Indian sabji and you will notice the dish tastes flatter, missing the pungent backbone mustard oil provides.

Think of it less as a replacement for your everyday oil and more as a specialty ingredient you keep alongside it, the way you would keep both olive oil and butter in a Western kitchen. A little goes a long way, especially in the roasted version, which is concentrated enough that a tablespoon or two changes an entire pot of tarkari.
