Simmer Down: Milagu Rasam Is the Immunity Booster You Need

Pepper, cumin, tomatoes, and tamarind are enough for this potent brew.

Despite it being a weekend, we were working. We had a deadline to meet. Those were the years when I had donned the hat of a software engineer, and my life revolved around deadlines and deliverables. It was past lunchtime, and the team decided to place an order for takeout. I was in Pune, a city 150 km away from Mumbai in India. While others were busy looking at the menu, my colleague Hari Sundaresan native to Tamilnadu, a state in Southern India, gave a forlorn look. " I want to eat my mother's rasam sadam [rasam rice]," he said. 

As a South Indian, I could relate to what he desired: comfort. Piping hot over-cooked rice, mashed with one's fingers and enveloped with a ladle of rasam is a hug on a plate. Hot and puckering, it is a staple in most South Indian lunches. Often kitchens are engulfed in the heady aroma of its tempering and spice mix. All that this minimalistic broth-like consistency dish requires is a tomato or tamarind extract as an acidifier and a medley of spices. While it is called rasam in Kerala and Tamilnadu, it goes by the name chaaru in Andhra Pradesh and saaru in Karnataka. It was called milagu thannir (pepper water) due to its essential ingredient, the highly prized pepper, which brought the Europeans to Indian soil. The late food historian KT Achaya writes in his book, Indian Food: A Historical Companion about Niccolao Manucci, a young Italian who visited India in 1654 and spent six decades practicing as a doctor. In his writings, Manucci refers to a brew that could have been rasam. "They sup a concoction which is somewhat water boiled with pepper."

As per Ayurveda, the ancient Indian system of medicine, consuming all the six fundamental tastes in every meal is mandatory. The no-frills rasam lends a shot of sourness to the palate. Rustic yet appetizing, rasam plays multiple roles in a meal: a palate cleanser, digestive, and an appetizer. It is a perfect transition when you have relished sambar rice and are yet to finish the meal by slurping thayir sadam or curd rice. Adapted to suit the Britishers' taste buds during the colonial era, meat and meat stock transformed the rasam into the Mulligatawny soup

"Mooligai Rasam is an interesting variety of Rasam made with herbs local to the region - like holy basil, Mexican mint, or lime leaves - commonly grown in backyards," says Janani Lakshminarayan, a writer, raconteur, and an avid cook. When under the weather with cold, fever, or stomachache, rasam is light on the stomach and acts as a perfect antidote. The soup-like thin potion seasoned with pepper, black mustard, and cumin has recently garnered attention as an immunity booster during the pandemic. Indian Chef Arun Rajadurai started serving rasam as an immunity booster soup to COVID patients in three hospitals in the USA. As per reports, the peppery broth went viral, daily selling about 500 cups.

Pineapple, gooseberry, raw mango, kokum - dried Garcinia Indica plant, and lemon are other souring agents used to prepare this versatile brew. Based on the season and availability of regional ingredients, neem tree blossoms and lentils boost rasam's potent flavors. In Chettinad, a region in Tamilnadu, the frugal dish attains prominence with the inclusion of crab for that hot and spicy nandu rasam. Every house has its unique rasam recipe. "We prepare Rasam every day in our household," says Janani. "Despite that, there are hardly any repetitions for at least two months. Varying the type and proportion of the ingredients according to the season and the availability yields many variations in taste, flavor, and strength of the Rasam." Such are the infinite varieties of Rasam.
