What Exactly Is Cold-Pressed Oil?
The return to cold-pressed sesame oil is a return to tradition. For centuries, oils in India were extracted using a 'ghani' or 'chekku'—a large wooden or stone press that slowly crushes seeds without generating heat. This mechanical process, often powered
by bullocks or a slow-turning motor, is gentle. Because it avoids high temperatures and chemical solvents like hexane, the oil that emerges is pure, unrefined, and packed with the original nutrients of the sesame seed. In contrast, modern refined oils undergo high-heat processing, bleaching, and deodorising. While this method increases yield and shelf life, it strips the oil of its natural vitamins, antioxidants, flavour, and aroma, which is precisely why health-conscious consumers are making the switch.
A Nutritional Upgrade for Your Pantry
The primary driver behind this trend is health. Increasing awareness of how industrial processing affects food has led many to question the refined oils that dominate supermarket shelves. Cold-pressed sesame oil retains a wealth of beneficial compounds that are often lost during refining. It is rich in heart-healthy monounsaturated and polyunsaturated fats, which can help manage cholesterol levels. It's also a powerhouse of antioxidants, particularly sesamol and sesamin, which protect the body's cells from damage. These oils preserve essential vitamins like Vitamin E and minerals that support everything from immunity to digestion. In essence, choosing cold-pressed is choosing the oil in its most wholesome, nourishing state.
The Flavour Factor
Beyond the health benefits, there's a powerful sensory reason for the shift: taste. Refined oils are intentionally neutral, but cold-pressed sesame oil boasts a distinctly rich and nutty flavour that can elevate a dish from ordinary to memorable. This authentic aroma is a critical component in many regional Indian cuisines, where the oil isn't just a cooking medium but a key flavouring ingredient. Chefs and home cooks alike are rediscovering that the deep, earthy notes of 'kachi ghani' oil can bring an unparalleled authenticity to everything from a simple dal tadka to complex curries and chutneys.
How to Use It in Your Kitchen
Integrating cold-pressed sesame oil into your daily cooking is simple. While it has a moderate smoke point suitable for light sautéing, its true potential shines when its flavour is preserved. Use it to create bold salad dressings by whisking it with rice vinegar, soy sauce, and a touch of honey. Drizzle it over roasted vegetables, noodles, or a bowl of soup just before serving to add a rich, aromatic finish. It also works wonderfully as a base for marinades for chicken, tofu, or vegetables, as its fat-soluble compounds help carry flavours like ginger and garlic deep into the food. Remember, its flavour is potent, so a little often goes a long way.
