What Is Jamu Kunyit Asam?
Jamu kunyit asam — literally "turmeric tamarind" — is one of the most iconic traditional Indonesian herbal drinks. Sold by mbok jamu (female jamu vendors) across Java for generations, this golden tonic is prized for its refreshing tartness, vibrant colour, and wide range of traditional health benefits. It is especially popular among women and is traditionally consumed to ease menstrual discomfort, support digestion, and keep the skin glowing.
The beauty of this recipe lies in its simplicity. You only need a handful of whole ingredients that are increasingly available at Asian grocery stores worldwide.
Ingredients (makes about 4 servings)
- 150g fresh turmeric root (or 2 tablespoons turmeric powder as a substitute)
- 50g tamarind paste (seedless, block tamarind is ideal)
- 800ml water
- 3–4 tablespoons palm sugar or coconut sugar (adjust to taste)
- A pinch of salt
- Optional: 1 stalk lemongrass, bruised
Step-by-Step Instructions
- Prepare the turmeric. Peel the fresh turmeric root and either grate it finely or blend it with a small amount of water to form a paste. If using powder, simply measure it out.
- Dissolve the tamarind. Soak the tamarind paste in about 200ml of warm water for 5 minutes, then squeeze and strain it to produce a smooth tamarind liquid. Discard the fibres and seeds.
- Simmer the base. Combine the turmeric paste, tamarind liquid, and remaining water in a small saucepan. Add the palm sugar, salt, and lemongrass (if using). Bring to a gentle simmer over medium heat, stirring until the sugar dissolves — about 8–10 minutes.
- Strain. Pour the mixture through a fine mesh strainer or muslin cloth into a jug or bottle, pressing out all the liquid.
- Taste and adjust. Add more sugar for sweetness or a squeeze of fresh lime for extra tartness.
- Serve. Drink warm immediately, or allow to cool and serve over ice. Keeps refrigerated for up to 3 days.
Tips for the Best Results
- Fresh turmeric root produces a far more vibrant colour and flavour than powder — seek it out if you can.
- Block tamarind (sold in Asian supermarkets) has a deeper, more complex flavour than pre-made tamarind concentrate.
- Palm sugar gives a more authentic caramel-like sweetness; brown sugar works as a substitute.
- Wear gloves when handling fresh turmeric — it stains skin and clothing intensely.
Why Drink Jamu Kunyit Asam?
In traditional Javanese practice, this tonic is consumed regularly rather than as a one-time remedy. Turmeric contains curcumin, a compound studied for its antioxidant and anti-inflammatory properties. Tamarind is rich in tartaric acid and provides a natural digestive aid. Together, they form a drink that is as nourishing as it is delicious.
Whether you are new to jamu or returning to a cherished family tradition, kunyit asam is the perfect starting point for your herbal wellness journey.
