Why is it essential to season your sambar/rasam with mustard seed?
In the Indian culinary system, there is an age-old tradition of seasoning (Oggarane in Kannada) in which mustard seeds are fried in a medium of either peanut oil or ghee in an iron ladle and added as topping to sambar, rasam and salads. This practice is unique to South India where seasoning is done routinely and sambar/rasam prepared without it is considered incomplete. Seasoning involves adding a dash of mustard seeds to a half-spoonful of oil/ghee in a preheated iron ladle in which the seeds pop up almost instantly. In some cases, jeera (cumin) and hing (asafetida) could also be added to impart a special flavor to food. The piping hot ladle is then taken out from the fire and dipped into sambar/rasam. Instantly, the fluid in close contact with the hot ladle simmers for a while. As the contents are mixed and served hot, one will love the spicy, aromatic rustic taste and fragrance that fried mustard adds to the meal.
When we look at the science behind this ancient practice, it’s pretty amazing as to how our ancestors knew so much about the health benefits of this common spice that they made seasoning with mustard compulsory in daily meals. Modern science tells us that mustard seed, belonging to Brassica family, is a rich source of several beneficial phytonutrients like isothiocyanate with anti-cancerous properties. The seeds contain large amounts of selenium, magnesium, phosphorus, copper and vitamin B1 which aid in preventing and reducing the severity of many ailments such as asthma, hypertension, heart problems and are useful in alleviating the symptoms of menopause in women.
