Mulligatawny Soup — The Rasam I Made to Remember

Labor Day weekend, and Amma dropped a bomb at Sunday dinner: she forgot the word for tamarind. Not in the way you forget a word when you're tired and it's on the tip of your tongue. In the way she forgot it completely, mid-sentence, and stared at the jar in her hand as if she'd never seen it before. She was making rasam — a dish she's made weekly for forty years — and she stopped and looked at the tamarind and said, "Pass me the..." and nothing came after. Appa filled in: "Puli." Tamarind. In Tamil. Amma blinked. "Yes. Puli." And she continued cooking as if nothing had happened. But something happened. I was sitting at the kitchen table ostensibly helping but really just watching (I've been doing a lot of watching lately — cataloging her movements, her instincts, the way she cracks mustard seeds by tilting the pan just so), and I saw the moment. The blankness. The gap. She's sixty-four. People forget words at sixty-four. It's normal. It's age. It doesn't mean anything. I told myself this all the way home. I told Raj about it in bed, trying to sound casual. "Amma forgot the word for tamarind today." Raj, the cardiologist, not the neurologist, said, "People forget words." "She's been using tamarind every day for forty years." "It's probably nothing. But if you're worried, she should get checked." I'm not worried. I'm filing this away. I'm putting it in the same mental drawer where I keep the time she drove past the temple turn, and the time she called Arvind by Appa's name, and the time she asked me how to make sambar powder — sambar powder, which she could make in her sleep, which she has made in her sleep. The drawer is getting full. I'm not ready to open it. Tonight I made rasam. Amma's rasam. With tamarind — puli — the ingredient whose name my mother forgot and then remembered, or pretended to remember, which might be the same thing. The rasam was good. Hot and sour and peppery, the way it's supposed to be. The way it's always been. I whispered the ingredients to myself as I cooked, like a prayer, like an incantation: tamarind, tomato, toor dal, pepper, cumin, garlic, curry leaves, mustard seeds, asafoetida, turmeric. I will not forget. Even if she does.

Rasam felt like the only thing I could make that night — not because it’s elaborate or impressive, but because it’s a recitation, a list I can hold onto: tamarind, tomato, toor dal, pepper, the whole litany of it. When I make it for guests, I usually simplify, pulling it toward something they recognize, a mulligatawny that borrows rasam’s bones but meets people where they are. Here’s that version — the one I made this week, while I was whispering to myself, while the drawer stayed shut.

Mulligatawny Soup (Rasam-Style)

Prep Time: 15 min | Cook Time: 35 min | Total Time: 50 min | Servings: 4

Ingredients

• 1/4 cup toor dal (split pigeon peas), rinsed
• 2 medium Roma tomatoes, roughly chopped
• 1 tablespoon tamarind paste (or a small lemon-sized ball of tamarind soaked in 1/2 cup warm water, strained)
• 1 teaspoon whole black peppercorns, coarsely crushed
• 1 teaspoon cumin seeds
• 4 cloves garlic, lightly crushed
• 1/4 teaspoon turmeric powder
• 1/4 teaspoon asafoetida (hing)
• 1 teaspoon salt, or to taste
• 3 cups water, plus more as needed
• For the tempering (tadka):
• 1 tablespoon ghee or neutral oil
• 1 teaspoon black mustard seeds
• 1 dried red chili, broken in half
• 10–12 fresh curry leaves
• 1 pinch asafoetida
• Fresh cilantro, for serving

Instructions

1. Cook the dal. Combine the toor dal with 1 1/2 cups water in a small saucepan. Bring to a boil, then reduce heat and simmer, partially covered, for 20–25 minutes until the dal is completely soft and falling apart. Mash thoroughly with the back of a spoon or a whisk until no lumps remain.
2. Simmer the base. Add the chopped tomatoes, tamarind paste, crushed black pepper, cumin seeds, garlic, turmeric, asafoetida, and remaining 1 1/2 cups water to the cooked dal. Stir to combine. Bring to a boil over medium-high heat.
3. Build the flavor. Reduce heat to medium and simmer uncovered for 10 minutes, stirring occasionally, until the tomatoes have broken down and the soup smells deeply fragrant. Add salt and taste — the rasam should be sour, peppery, and savory in balance. Add more water if the soup is too thick; it should be thin and broth-like.
4. Make the tadka. In a small skillet or ladle over high heat, warm the ghee until it shimmers. Add the mustard seeds and wait — tilting the pan gently — until they begin to pop and splutter. Add the dried red chili, curry leaves (stand back; they will spit), and the pinch of asafoetida. Swirl once, then immediately pour the entire contents of the pan over the soup.
5. Finish and serve. Stir the tadka into the soup. Taste once more for salt and tamarind. Ladle into bowls and garnish with fresh cilantro. Serve very hot, alongside steamed rice or on its own as a restorative broth.
