Sarson Wali Aloo Sabzi - Cooked in Cold-Pressed Mustard Oil

Read time: 7 min | Category: Recipes

This dish has been made in North Indian kitchens for generations, and for good reason: it's fast, it uses pantry staples, and when made with genuine cold-pressed mustard oil, it has a flavour that's impossible to replicate with refined substitutes. Rulife Cold Pressed Mustard Oil is extracted from black mustard seeds using a wooden ghani press at low temperature, preserving the natural allyl isothiocyanate compounds that give mustard oil its signature bite.

What You Need

• 4 medium potatoes, boiled and cubed
• 2 tbsp Rulife Cold Pressed Mustard Oil
• 1 tsp mustard seeds (rai)
• 1 tsp kalonji (nigella seeds)
• 2 dried red chillies
• 1 medium onion, thinly sliced
• 1/2 tsp turmeric
• 1 tsp coriander powder
• 1/2 tsp amchur (dry mango powder) or squeeze of lemon
• Salt to taste
• Fresh mustard greens or coriander for garnish (optional)

How to Make It

1. Heat Rulife Cold Pressed Mustard Oil in a kadhai or heavy pan on medium-high flame. Cold-pressed mustard oil has a smoke point around 250°C, so heat until it just begins to smoke lightly - this is the traditional kacha tel step that mellows the raw pungency.
2. Reduce to medium heat. Add mustard seeds and kalonji - let them crackle for 10 seconds. Add dried red chillies.
3. Add sliced onion and cook until translucent, about 4-5 minutes.
4. Add turmeric and coriander powder. Stir well and cook the masala for 1 minute.
5. Add boiled potato cubes. Toss to coat evenly. Cook uncovered on medium flame for 5-6 minutes, letting the potatoes pick up slight colour on the edges.
6. Add salt and amchur. Toss once more. The oil should be visible glistening on the sabzi - that's correct and intentional.
7. Serve hot with rotis or as a side with dal-chawal.

Chef's Tips

• Heat the oil first. Raw cold-pressed mustard oil has intense pungency. Heating it briefly to the smoke point removes the harsh edge while keeping the deep flavour. Don't skip this step.
• Use kalonji. This combination of mustard seeds and kalonji is classic Bengali-inspired and rounds out the flavour profile of the mustard oil beautifully.
• Don't overcrowd the pan. Give the potato cubes space to develop a light crust. Stirring too frequently makes them mushy and pale.

Why Cold-Pressed Mustard Oil Changes This Recipe

Refined mustard oil has most of its sulphur compounds removed during processing - these compounds are exactly what give sarson wali aloo its character. Rulife Cold Pressed Mustard Oil retains natural glucosinolates and omega-3 fatty acids (alpha-linolenic acid) that are stripped away by high-heat refining. The result is an oil that isn't just a cooking medium - it actively contributes to the taste and nutritional value of the dish.

It's also rich in monounsaturated fats and has a naturally long shelf life due to its antioxidant content, meaning one bottle goes a long way.

Frequently Asked Questions

Why does mustard oil need to be heated before cooking?

Raw cold-pressed mustard oil contains allyl isothiocyanate, which gives it a sharp, nose-clearing pungency. Briefly heating the oil to its smoke point converts this compound into milder aromatic ones, making the oil more palatable for cooking while retaining its distinctive flavour.

Is mustard oil safe for cooking?

Yes. Mustard oil has been used for centuries in North Indian, Bengali, and Rajasthani cooking. It has a high smoke point, is rich in heart-healthy omega-3 and omega-6 fatty acids, and contains natural antifungal and antibacterial properties.

Can I use yellow mustard seeds oil instead of black?

Rulife uses black mustard seeds, which are pungent and more aromatic than yellow mustard. Yellow mustard oil is milder and more common in European cooking. For this recipe, the black mustard variety is the authentic choice.
