What is Thambuli?
Hailing from the coastal and Malnad regions of Karnataka, a Thambuli (or Thambli) is a traditional Ayurvedic-inspired yogurt-based drink or side dish. The name is derived from “thampu,” which literally translates to “cool” or “cold.” It’s designed to balance body heat, aid digestion, and provide a refreshing kick to your meal.

Looking for everyday Indian meals
Think of it as the more sattvic cousin of the North Indian Raita or Greek Tzatziki. It is like a savoury cold soup. There are different types of tambuli recipe – shunti (ginger) tambuli, karibevu (curry leaf) thambuli or the jeerige (cumin) thambuli.
Why You’ll Love It
- No-Cook Magic: Except an easy tadka, there is not much cooking involved.
- Gut-Friendly: Packed with probiotics from the curd and digestive enzymes from cucumber. There is no gluten.
- Quick: Takes less than 20 minutes from fridge to table.
Ingredients You’ll Need
The Base:
- Cucumber (Southekayi) peeled and deseed (if using a large, mature cucumber).
- Coconut, freshly grated and not dried or dessicated (essential for that authentic creamy texture).
- Curd or Indian Buttermilk fresh and whisked.
- Green Chilies, Cumin Seeds (Jeera), Ginger, and Black Peppercorns
- Fresh Coriander Leaves for the bright green colour.
- Salt to taste.
The Tempering (Tadka):
- Ghee or Sesame Oil works, but ghee is traditional and more fragrant.
- Mustard Seeds, Cumin Seeds, Curry Leaves, Dried Red Chilli
How To Make Cucumber Tambuli
1. The Flavour Paste
- In a small blender jar, add the chopped cucumber, grated coconut, green chilies, cumin seeds, black peppercorns, ginger, coriander leaves, and a splash of water. Grind this into a very smooth, fine paste.
2. Whisk Curd
- In a medium bowl, combine the whisked curd or buttermilk, cucumber paste, and salt.
- If the mixture is too thick, you can thin it out with a little water or buttermilk; Thambuli is typically thinner than a standard raita.
3. The Tempering
- Heat oil in a small pan.
- Once hot, add the mustard seeds and let them splutter.
- Add the cumin seeds, red chili, and curry leaves. Once the leaves are crisp and the aroma fills the kitchen, pour this hot tempering directly over the cucumber tambuli.
Mix nicely and Cucumber Tambuli is ready to serve.
Serving Suggestion
Southekayi (cucumber) Thambuli is traditionally served at the very beginning of a traditional South Indian meal as an appetizer like rasam.
Pour it over a small mound of hot steamed rice and enjoy it as a soothing first course. It also works beautifully as a standalone cold soup or a side dish for vegetable pulao, or honestly just drink it cold from a glass on a 40-degree afternoon.

Hina’s Tried and True Tips
- Freshness Matters: Use fresh, homemade curd that isn’t too sour. If the curd is very sour, add a tiny pinch of sugar or jaggery to balance it.
- Do not heat: Heat kills the cooling properties. Tambuli is designed to work with your body in summer.
- If you want to make a vegan thambuli recipe, you can easily swap the dairy yogurt for unsweetened cashew yogurt or diluted coconut milk with a squeeze of lemon for that necessary tang.
