Curd Rice Recipe: Thayir Sadam (தயிர் சாதம்) in 45 Minutes

What Is Curd Rice (தயிர் சாதம்)?

Curd rice (தயிர் சாதம், thayir sadam) is a South Indian comfort food made by mixing mushy cooked rice with thick fresh curd, butter, and a mustard seed tempering with curry leaves. It is eaten as a cooling lunch, temple prasadam, and the traditional last course of a South Indian thali. Tamil Nadu, Andhra Pradesh, and Karnataka all claim it as their own.

I grew up eating thayir sadam every afternoon. My mother used to say no lunch was complete without it. She was right. The creamy, tangy, mildly spiced rice settles the stomach after a heavy course of sambar rice. The step most people miss is mashing the rice while it is still hot and adding milk. That is what gives it the temple-style texture.

Curd rice nutrition, per 100 g: about 113 kcal, 2.9 g protein, 14 g carbohydrate, 5 g fat and 63 mg calcium. One serving of this recipe is roughly 175 g, so that is about 195 kcal, 5 g protein and 110 mg calcium a bowl. Makes 4 servings.

How we got those numbers: added up from IFCT 2017 (ICMR-NIN) — milled raw rice at 1,491 kJ and 7.94 g protein per 100 g, whole cow milk at 305 kJ, 3.26 g protein and 118 mg calcium per 100 g — plus the butter and oil in the tempering, divided by four servings. Curd keeps the protein of the milk it was set from; fermentation only changes the sugar. An earlier version of this page said 12 g of protein a serving, which was about two and a half times too high.

What Ingredients Do You Need?

Curd rice needs short-grain rice (Sona Masoori or Ponni), thick fresh curd, whole milk, butter, and a traditional South Indian tempering of mustard seeds, urad dal, curry leaves, and green chili. Optional garnishes include cucumber, pomegranate, and carrot.

Use short-grain rice, not basmati. Short grains get mushy when overcooked, which is exactly what you want for curd rice. Basmati stays too firm and grainy.

For the curd, I rely on the InstaCuppa Automatic Curd Maker, which is sold out as of 13 September 2026. Fresh curd has a mild tang versus the sourness of store-bought, and it is thick enough to coat each grain of rice.

How to Make Curd Rice Step by Step

Curd rice takes about 45 minutes, of which 20 minutes is active work. Three steps matter. Overcook the rice. Mash it hot with milk. Cool it before the curd goes in. Curd added to hot rice loses its live bacteria.

1. Wash 100g rice and pressure cook with 400ml water for 5 whistles on medium (10 min).
2. Mash hot rice with a ladle until mushy. Stir in hot boiled 120ml milk + 15g butter. Cool to room temp (20-25 min).
3. Whisk 240ml fresh curd until smooth. Mix into cooled rice with 1 tsp salt. Adjust creaminess with more curd.
4. Make tadka: Heat 1 tsp oil, add mustard seeds (splutter), urad dal (golden), curry leaves, green chili, and hing.
5. Pour hot tempering over the curd rice. Combine well. Garnish with pomegranate, cucumber, or coriander. Serve chilled.

What Mistakes Should You Avoid?

The biggest mistake is adding curd to hot rice. Heat kills the live Lactobacillus in the curd. You are then eating plain rice with dead bacteria in it. Cool the rice to room temperature first, then mix the curd in.

• Using sour or old curd: Ruins the mild flavor. Always use fresh homemade curd.
• Skipping the mash + milk step: Rice stays grainy instead of creamy temple-style.
• Adding cold tempering: Oils do not infuse properly. Pour the tadka hot for maximum aroma.
• Under-cooking rice: Curd rice needs mushy rice for even coating. Overcook on purpose.

Science note: cooling cooked rice really does change its starch. Researchers measured resistant starch in freshly cooked white rice at 0.64 g per 100 g, in rice cooled 10 hours at room temperature at 1.30 g, and in rice chilled 24 hours at 4°C and reheated at 1.65 g. In 15 healthy adults the chilled-and-reheated rice produced a significantly lower blood sugar response than the fresh rice — Sonia, Witjaksono and Ridwan, Asia Pacific Journal of Clinical Nutrition 2015;24(4):620-5. That is a real effect, but it is grams, not a transformation.

What Are Some Curd Rice Variations?

Curd rice has three classic variations - temple-style with extra ghee, a fruity hung curd version with pomegranate, and a family-size Greek twist with grated carrot and peanuts.

• Temple-Style (Kovil Thayir Sadam): Extra ghee tempering + ginger powder, no veggies. Authentic shrine-style. About 200 kcal/serving.
• Fruity Hung Curd Version: Use Greek Yogurt Maker 1100 ml, Rs 999 for thick hung curd. Add pomegranate and mango. About 160 kcal/serving.
• Family Greek Twist: Greek Yogurt Maker 2.5 litre, Rs 1,799 for a double batch of thick curd. Add grated carrot + peanuts. About 190 kcal/serving.

Is Curd Rice Good for an Upset Stomach?

How long curd rice takes to digest. A plain rice-and-curd meal is among the faster things to leave your stomach — soft, low in fat and low in fibre are the three properties that speed gastric emptying. Add ghee, peanuts or a heavy tempering and it slows down. If you are eating it for an upset stomach, leave those out.

On an empty stomach. There is nothing in curd rice that needs a base under it. If you tolerate dairy, a bowl first thing is fine. If milk makes you bloat, curd is usually still fine, because the bacteria have already eaten much of the lactose.

When to skip it. Curd rice will not help a fever with a sore throat, and it will not fix food poisoning on its own. If there is blood, a high fever, or the symptoms run past two days, that is a doctor, not a bowl of rice.

How Long Does Curd Rice Last?

Curd rice keeps for 24 to 48 hours in the fridge, in an airtight box. It tastes best on Day 1 and is still good on Day 2. The flavours meld overnight, and the rice picks up a little more resistant starch as it sits cold (0.64 g to about 1.65 g per 100 g in the study above). Great for lunchboxes. Avoid keeping beyond 48 hours as it gets too sour.
