What 'Cold-Pressed' Really Means
Before we get into the hacks, what’s the big deal with 'cold-pressed'? Unlike refined oils, which use high heat and chemical solvents that strip away nutrients, cold-pressed oils are extracted by mechanically crushing seeds at low temperatures. This traditional
'ghani' or 'chekku' method preserves the oil's natural flavour, aroma, and, most importantly, its antioxidants and healthy fats. Think of it as the difference between fresh-squeezed juice and juice from concentrate; one is simply closer to its natural state. This means more flavour and nutrients in every drop.
Mustard Oil: The Pungent Powerhouse of the North
Mustard oil is the soul of many North and East Indian cuisines, from Punjabi curries to Bengali fish preparations. Its signature pungency comes from a compound called allyl isothiocyanate. The hack to taming this sharp flavour for everyday cooking is to heat the oil until it just begins to let off its first wisp of smoke, then reduce the flame before adding your spices. This mellows the flavour into a warm, nutty aroma. With a high smoke point of around 250°C, it's perfect for deep-frying crispy pakoras, making pickles, or preparing a classic 'tadka' for dal. For an authentic Bengali 'Shorshe Maach' (mustard fish curry), marinating the fish in a mix of mustard oil and spices first not only tenderises it but also builds an incredible depth of flavour.
Groundnut Oil: The Versatile Staple of the West
In Gujarat and Maharashtra, groundnut oil is the undisputed king of the kitchen. Its mild, nutty flavour makes it incredibly versatile, and it doesn't overpower the delicate balance of sweet, sour, and spicy notes found in Western Indian cuisine. While its smoke point is lower than mustard oil, at around 160-170°C, it's stable enough for most daily Indian cooking methods, including tempering, sautéing, and light frying. The ultimate hack is using it to fry snacks like 'fafda' or 'chakli'; it gives them a clean, crisp texture without leaving them greasy. For a classic Gujarati 'undhiyu' or Maharashtrian 'bharli vangi' (stuffed aubergine), using cold-pressed groundnut oil adds a subtle richness that ties all the spices together beautifully.
Sesame Oil: The Nutty Elixir of the South
Known as the 'queen of oils,' sesame oil (til ka tel) is a cornerstone of South Indian cooking and Ayurvedic tradition. Cold-pressed sesame oil has a distinct nutty flavour and a medium smoke point, around 177°C, making it ideal for 'tadkas' and light sautéing rather than deep frying. A key hack is to use it as a finishing oil. A drizzle over a finished dish like 'pulihora' (tamarind rice) or a simple bowl of noodles adds a layer of rich, aromatic flavour. In many South Indian homes, it's the go-to for tempering chutneys and dals with mustard seeds and curry leaves. You can also make a fantastic salad dressing by whisking it with rice vinegar, ginger, and a touch of soy sauce.
