Lemon Rasam

Rasam, a thin, lemony soup made with toor dal, a type of split pea, is served as a starter in South Indian households. Purchase toor dal in Indian grocery stores and online, or look for gold lentils in natural food stores. Curry leaves are worth seeking out for the remarkable flavor they add.



Ingredient Line: 
¼ tsp. ground turmeric
Ingredient Line: 
⅔ cup dry toor dal (split pigeon peas)
Ingredient Line: 
1 Tbs. grated fresh ginger (from 1-inch piece)
Ingredient Line: 
2 serrano chiles, stemmed, seeded, and minced
Ingredient Line: 
1 14.5-oz. can plum tomatoes, drained and diced
Ingredient Line: 
¾ tsp. salt
Ingredient Line: 
2 tsp. ghee
Ingredient Line: 
1 tsp. brown mustard seeds
Ingredient Line: 
½ tsp. asafetida powder
Ingredient Line: 
1 red Kashmiri chile (dried red Indian chile), or any hot dried red chile, halved
Ingredient Line: 
10 curry leaves, optional
Ingredient Line: 
½ tsp. ground cumin
Ingredient Line: 
½ tsp. ground black pepper
Ingredient Line: 
¼ cup lemon juice


1. Combine toor dal with 4 cups water and turmeric in medium saucepan. Bring to a boil over medium heat. Reduce heat to medium-low, partially cover, and simmer 45 minutes, or until toor dal is soft. Transfer to blender or food processor, and blend until smooth. Measure, and return to saucepan. Add enough water to make 5 cups.

2. Stir in ginger, serrano chiles, tomatoes, and salt, and bring to a boil over medium heat. Reduce heat to medium-low, and simmer 5 minutes to marry flavors, stirring occasionally.

3. Meanwhile, heat ghee in skillet over medium heat. Add mustard seeds; asafetida powder; red chile; curry leaves, if using; cumin; and pepper. Cover and heat 1 to 2 minutes, or until mustard seeds begin to pop. Pour into soup. Remove soup from heat, and stir in lemon juice. Season with salt and pepper, if desired. Serve garnished with chopped cilantro.

We can add a teaspoon of grated coconut as seasoning

Being vegan, many of our South Indian dishes are amazing for me! All I do is avoid the ghee and I'm set :) Thanks for the recipe!
