My mother still keeps two bottles of oil next to the stove, one refined and one mustard, and she reaches for the mustard one whenever she’s making anything from Bengal or Punjab. Growing up, I thought it was just about taste, that sharp, pungent kick you get when it hits a hot pan. It wasn’t until I started cooking on my own that I realized how much thought actually goes into which oil she picks for which dish.
What is Mustard Oil?
Mustard oil, known as sarson ka tel, is extracted from mustard seeds and has been a kitchen staple across North and East India for generations. It has a distinctive pungent aroma and a sharp, slightly spicy flavor that mellows once it’s heated to its smoking point. Beyond cooking, it’s also long been used topically for skin and hair care, which says a lot about how central it is to everyday Indian households.
Where Mustard Oil Fits in Indian Food Culture
Mustard oil is especially dominant in the cuisines of Bengal, Punjab, Bihar, and Uttar Pradesh, where it’s the default cooking fat for everything from fish curries to pickles. In Bengali cooking, it’s practically non-negotiable for dishes like shorshe maach, where the oil itself contributes as much flavor as the mustard paste. It’s also the traditional base for most Indian achaar, or pickles, since its natural preservative qualities help pickled vegetables stay fresh for months without refrigeration.
The Real Benefits
- Mustard oil is rich in monounsaturated and polyunsaturated fats, including a healthy ratio of omega-3 and omega-6 fatty acids
- It contains allyl isothiocyanate, a compound with antibacterial and antifungal properties
- It has a high smoking point, which makes it well-suited to deep frying and high-heat cooking without breaking down as easily as some other oils
- Mustard oil is often used in massage for joint and muscle discomfort, and many people find it soothing when warmed slightly
- It contains vitamin E, which supports skin health when used topically
How to Use Mustard Oil
- Heat it until it reaches its smoking point before adding other ingredients; this mellows the sharp raw flavor
- Use it as the base for pickles and chutneys, where its preservative qualities really shine
- Try it in fish curries or vegetable stir-fries for an authentic Bengali or Punjabi flavor profile
- Use it in moderation alongside other oils rather than as your only cooking fat, for a more balanced diet
- Look for cold-pressed, unrefined varieties for the most robust flavor and nutritional profile
Mustard oil is one of those ingredients that shows how traditional Indian cooking was never just about taste, it was also about practicality, preservation, and using what worked well for the local climate and diet. Keeping a bottle in your kitchen alongside your everyday cooking oil is a simple way to bring some of that traditional wisdom back into your meals.
