 What is Rasam?

Rasam is South India's award-winning contribution to the incredible world of Sour Soups! It's South Indian hot and sour soup - hot from the mélange of spices in Tangy Rasam PODI and tempering, and sour from the traditional combination of tamarind + tomatoes. 

Lets talk science!

Scientifically it is a spicy, acidic broth with an aromatic tempering!

Using this basic principle, culinary creatives have riffed a million rasam variations - like mango rasam, tomato rasam, pineapple rasam, fresh coriander rasam, lemon rasam, chicken rasam etc...the list goes on. 

While the spices tend to be quite constant - usually a combination of coriander seeds, black pepper, cumin, turmeric and chilies, the acidic component is varied! You can use any sour fruit - like tomatoes, mangoes, tamarind, lemon, pineapple or even apple cider vinegar. 

The broth can be simply water or vegetable stock or chicken broth. 

A tempering is a must for rasam! Bloom whole spices in oil to release their flavor molecules, and add incredible aromatics - like garlic, and another earthy layer of curry leaves if you have them.

Easy Breezy Recipe

COOK TIME: 30 mins || Servings: 4-6


  • 3 medium-sized tomatoes, boiled and peeled or 1 can of San Marzano tomatoes
  • 1 quarter sized ball of tamarind / 1tbsp tamarind paste
  • 500ml water
  • 1 tbsp Tangy Rasam PODI
  • 1 tsp Crispy Garlic PODI 
  • 1 tbsp Curry Leaf PODI 
  • 2 tbsp ghee or olive oil
  • 1 tsp coriander seeds, optional but aesthetic
  • 2-3 dry red chilies (any low to medium-spicy kind), optional but aesthetic
  • 4 garlic pods
  • 1 tsp mustard seeds, optional but aesthetic
  • 1 fresh bunch of coriander leaves/cilantro, for garnish


Step 1 - Prepping the tomato base

Easiest method: Take a can of good quality canned tomatoes like San Marzano tomatoes. 

Medium-effort method: Cut tomatoes into four quarters, boil tomato quarters in a medium sized pan with 500 ml of water. Once the water comes to a boil, start the timer, cook for 5 mins. Turn off heat. Let it cool to room temperature.

High-effort method: Place X shaped cuts on either the either end of tomatoes. Place slit tomatoes in a medium pan, in an excess of water (until tomatoes are submerged). Once sufficiently boiled (~5 min of rolling boils), the peel will start to curl. Scoop tomato out of the water and peel. Let it cool to room temperature. 

Step 2 - Making your spice blend

In a bowl, mix the following PODIs: 

Step 3 - Infusing tomato base with spices

Blend cooled (and peeled) tomatoes with spice mix above, 500 ml water and blend with an immersion blender. Some (5%) tomato chunks are ok. Bring this mixture to boil, simmer for 10 mins on medium heat. 

Step 4 - Tempering!

  • Keep crushed and chopped garlic ready
  • In 2 tbsp of ghee/olive oil, add mustard seeds, coriander seeds, chilies, crushed garlic. Let garlic brown! 
  • Pour tempered spices into rasam! Garnish with freshly chopped cilantro - remember to include cilantro stems (that's where most of the flavor is!)
