Kollu Rasam Recipe | Easy Horse Gram Rasam (Healthy South Indian Style)
⭐ About This Recipe
This Kollu Rasam (Horse Gram Rasam) is one of my favourite comfort dishes, especially during winter. In our South Indian homes, kollu is something we always make when we want warmth, better digestion, and a simple homemade immunity boost with simple available ingredients at home .
I love this recipe because it’s so easy, flavourful, and naturally healthy. The boiled kollu water, garlic, pepper, and jeera give such a soothing taste perfect for days when you feel heavy, tired, or when the weather is cold. Even if you are new to horse gram, this kollu rasam is the best way to start.
This is the kind of rasam you can sip like a soup or mix with hot rice… either way, it gives a very homely, healing feel. I always make it during winter or whenever anyone at home needs a light and healthy meal.
Kollu Rasam (Horse Gram Rasam)
Ingredients
Equipment
Method
- Soak 100g horse gram in water for 8 hours
- Pressure cook for 6–7 whistles or boil until soft.
- Reserve the boiled horse gram water.
- Take 1–2 teaspoons of the boiled horse gram for grinding.
- In a mixer, add cumin seeds, pepper seeds, and 2 red chillies.
- Grind once, then add 1–2 tsp boiled horse gram.
- Coarsely grind and keep aside.
- Heat oil in a pan.
- Add mustard seeds and let them splutter.
- Add 2 broken red chillies and smashed garlic (with skin).
- Saute until garlic turns slightly brown.
- Add the ground paste and saute gently.
- Add the finely chopped tomato and turmeric powder.
- Pour a little water and cook until tomatoes soften.
- Add the reserved horse gram water.
- Boil for about 10 minutes until it comes to a rolling boil.
- Add tamarind extract (small lemon-sized tamarind soaked & pulp removed).
- Add salt to taste.
- Boil lightly until you see bubbles forming.
- Add chopped coriander leaves and a pinch of jaggery.
- Turn off the flame.
- Serve hot with steamed rice or sip as a warm soup.
Notes
- Adjust tamarind according to your taste. Since we are adding a ripe tomato, the rasam will already have some natural tanginess — so add tamarind gradually and balance it based on your preference.
- You can add extra garlic or pepper if you want a stronger flavour and more warmth, especially during winter.
- Do not overboil after adding tamarind, as it can slightly change the taste of the rasam.
- Adjust salt carefully. While boiling horse gram, we usually add a little salt, so the horse gram water already contains salt. Always add salt at the end after tasting.
- Leftover boiled horse gram can be reused to make kollu chutney, kollu sundal, or even added back to the rasam for extra thickness.
💡 Tips for This Kollu Rasam Recipe
- Soak kollu for at least 8 hours so it cooks faster and becomes easier to digest.
- Always use the boiled kollu water — this gives the rasam its authentic flavour and is very nutritious.
- Grind the spices coarsely, not fine. The texture of cumin, pepper, and kollu gives the best rasam taste.
- Smashed garlic with skin adds strong aroma and helps with digestion, especially in winter.
- Boil well before adding tamarind. This helps the flavour develop properly.
- Don’t overboil after adding tamarind. Too much boiling can slightly affect the taste.
- Balance the tanginess. Since we use ripe tomato + tamarind, always start with less tamarind and adjust as needed.
- Salt carefully. Horse gram water already contains some salt from boiling, so always add salt at the end after tasting.
- Add a pinch of jaggery to bring all flavours together naturally.
- Use leftover kollu wisely: You can use the boiled kollu to make kollu chutney, kollu sundal, or even for kollu paruppu (recipe will be updated shortly).
- Quick tamarind trick: If you want tamarind pulp faster, boil the tamarind in water till it comes to a rolling boil, cool it down, then extract the pulp. It releases flavour instantly.
FAQs – Kollu Rasam (Horse Gram Rasam)
Can I replace tamarind with lemon?
Not recommended for kollu rasam. Lemon gives a fresh citrus flavour, whereas kollu rasam needs a warm sourness from tamarind. It won’t taste authentic.
Why is my Kollu Rasam not aromatic?
This usually happens if the spices were ground too fine or if garlic wasn’t sauteed well. Coarse grinding and roasting garlic gives the best aroma.
Is Kollu Rasam suitable for kids?
Yes very much, but reduce pepper and chilli if serving to younger children. The rasam is light, comforting, and easy to digest.
Can I make Kollu Rasam without tomato?
Yes, you can make kollu rasam without tomato. Simply increase a little tamarind for tanginess, or keep it mild if you prefer a light, peppery rasam.
Can I make this rasam without soaking horse gram?
Soaking gives the best texture and cooks the horse gram evenly. But if you forget to soak, you can still cook it — just soak the horse gram in hot water for 30minutes and while boiling ,increase the pressure cooker whistles to 10–12 so it cooks completely.
Can I make Kollu Rasam without garlic?
Yes, you can skip garlic if you want. But garlic adds a beautiful flavour and helps digestion, especially in winter.
