What is rasam?
Rasam is the authentic side dish recipe in South Indian cuisine. Without this dish, the South Indian meal will not get completed. This is a thin, soup-like food that usually served with rice. And at times, served as a soup and advised by elders in our family to drink it after a heavy meal.
Here in the United States, I have seen many Indian restaurants have rasam as their soup menu. This is sour with the bold flavors of black pepper, garlic, and cumin seeds.

How to make rasam powder?
I wanted to make this recipe as simple as possible with easy to find ingredients and remains very authentic always. We will see the ingredients and their possible substitutions that will not affect the dish's original taste and flavor.
Authentically the ingredients are used to sun-dried before grinding. But its sun drying method is not always possible in the state like Pennsylvania, where it would cover with the cloud most time. So we have opted for the pan roasting method, which is reliable and relishes great as well.
The ingredients.
Toor dal. This adds the density and little protein to the dish. Indian stores carry this at approximately $4 for two pounds. Which is good enough, you can use it for making dal or lentil curry.
If you are looking into Indian recipes, I would say, its a good investment. Otherwise, you may skip using it, and still, this spice mix will serve the purposes.
Black Pepper. The rasam cannot be made without the black pepper, where this ingredient is originated in South India. I would strongly advise using the whole black pepper, which has got an intense flavor and that hits your tongue while eating.
Cumin seeds. A nice flavor enhancer. The other side of the world using this spice for centuries. You may refer Healthline for more advantages of using cumin seeds. Most stores carry cumin seeds either in the spices aisle or in specialty isle. Online stores also a good place to locate this spice.
Coriander seeds. Another important ingredient is responsible for aroma in this mixture. It provides depth for this classic Indian recipe. Never skip this, and you will pat yourself for whipping up a rich and best rasam that everyone will give their heart for.
Optional ingredients. Asafoetida and turmeric powder. The other two unique Indian ingredients that I really wanted to mention here. Since this rasam powder recipe is multifunctional and I have not mentioned here.
To have this recipe more adaptable to various dishes, I have not included it here. These two ingredients are already in powder form, you may add these while making rasam or individual recipes.
The directions.
Dry roast. As I have already mentioned this can be done either by sun-drying or by pan roasting. The main purpose of dry roasting is to remove any moisture content to make it more flavorful. We are making today's recipe is by roasting in the pan.
In a pan all the ingredients together, coriander seeds, cumin seeds, black pepper, and Toor dal. Dry roast until it changes its color slightly.
Cool. Allow it to cool to room temperature.
Grind. Add the dry roasted ingredients to the blender and grind it to a coarse powder. Make sure not to grind finely, as this will destroy the spice's natural flavors.
Store. Transfer it in the airtight container for further use.
How to store?
Transfer the ground mixture to an airtight jar for later uses. Narrow-mouthed airtight glasswares are advisable to store the spice mixes. If you have made in larger quantity, divide and store them in a different container to avoid any loss of aroma in handling the jars.
I usually freeze the spice powder. And transfer to smaller jars to store in the kitchen shelves for a single month usage. This way the aroma is preserved for a year-long usage.
How to use this Indian spice mix?
- Apart from making rasam, you can also use this as spice powder for making any Indian curries. We can use this spice mix whenever a recipe calls for curry powder.
- If you are making an Indian style meal, whether a simple vegetarian curry or meat curry, we can confidently add this spice mix.
- This is a great addition when we try to bring Indian flavors in any curry. How to do? Just sprinkle this spice mix before removing it from the heat.
- This can also be used as rub while marinating chicken or seafood. This blends rightly well with the meat and acts as a flavor booster that tingles your sensations.
