Step 1: Prepare Rasam Base

In a bowl, take 1 chopped ripe red tomato. Add salt to taste. Crush the tomato well with a pestle or your hand.

Step 2: Extract Tamarind Juice

Take a lemon-sized piece of tamarind and soak it in a cup of water. Extract the juice by squeezing the tamarind. Add another cup of water and extract any remaining juice, then discard the pulp.

Step 3: Combine Rasam Ingredients

Pour the tamarind extract into the crushed tomato. Add a pinch of turmeric powder, 1 teaspoon of homemade sambar powder, and a large pinch of hing (asafoetida).

Step 4: Boil Rasam

Heat the rasam mixture on a low flame until it comes to a boil and becomes frothy at the sides.

Step 5: Prepare Rasam Spice Mix

In a mortar, take 3 garlic cloves (optional), 1/2 teaspoon of whole black pepper, and 1/2 teaspoon of jeera (cumin seeds). Crush them together to a coarse powder.

Step 6: Add Spice Mix and Coriander

Once the rasam is frothing and rising, add the crushed garlic, pepper, and jeera mix to it. Then, add some fresh coriander leaves.

Step 7: Temper the Rasam

In a small tempering ladle, heat 1 teaspoon of ghee. Add 1/2 teaspoon of mustard seeds, 1 dry red chili, and a few curry leaves. Once the mustard seeds splutter and the chili darkens, pour this tempering over the rasam. Immediately cover the rasam to retain the aroma and flavors.

Step 8: Prepare Potatoes for Frying

Take 3 boiled, peeled, and chopped potatoes. Add a pinch of turmeric powder, salt to taste, 1 teaspoon of Kashmiri chili powder, 1 teaspoon of homemade sambar powder, and 1 teaspoon of rice flour. Mix everything well so that all the potato pieces are coated with the spices.

Step 9: Temper for Potato Fry

Heat 2 tablespoons of oil in a cast iron kadai. Add 1/2 teaspoon of mustard seeds, 1/2 teaspoon of urad dal, a little bit of hing (asafoetida), and a few curry leaves. Let them splutter and fry until fragrant.

Step 10: Fry the Potatoes

Add the coated potatoes to the kadai. Gently mix with a light hand. Allow the potatoes to cook and roast until they turn golden brown and crispy. Do not mix too often to achieve the perfect texture.

Step 11: Prepare Curd Rice Base

Take 1 cup of hot cooked rice (boiled in a pressure cooker along with potatoes). Mash the rice well. Add a little bit of salt, 1 cup of fresh curd, and 1/4 cup of boiled and cooled milk. Mix everything well until the curd rice is creamy and has a slightly flowing consistency.

Step 12: Temper the Curd Rice

In a small tempering ladle, heat 1 teaspoon of oil. Add 1/2 teaspoon of mustard seeds, 1 finely chopped green chili, 1/2 teaspoon of grated ginger, and a few curry leaves. Once the mustard seeds splutter and the ingredients are fragrant, pour this aromatic tempering on top of the curd rice.

Step 13: Serve the Lunch Combo

Serve the steaming hot rice with a generous portion of rasam on top. Serve the creamy and tempting curd rice in a separate bowl. Arrange the crispy golden potato fry on the side. Optionally, serve with a bit of citron pickle for an added tangy flavor. Enjoy this comforting South Indian lunch!

• Garlic is optional for the rasam; you can omit it if you don't prefer it.

• Use a cast iron kadai for the potato fry to achieve a perfect crispy texture.

• Do not mix the potatoes too often while frying to allow them to roast and crisp up properly.

• Cover the rasam immediately after tempering to retain all the flavors and aroma.

• For curd rice, ensure the rice is mashed well and the consistency is creamy and slightly flowing, not too thick.

• The homemade sambar powder used is versatile and can be used for other dishes like sambar, vegetable curries, and vatha kuzhambu.
