• 1/2 tsp cumin seeds
• 1/4 tsp fenugreek seeds (optional but traditional)
• 2 dried red chiles
• 10 curry leaves

Step-by-Step Instructions

Step 1: Soak the rice and lentils

In two separate bowls, add:

• Bowl 1: 2 cups (400 g) parboiled rice
• Bowl 2: 1/2 cup (100 g) urad dal + 1/2 tsp fenugreek seeds

Cover each with at least 2 inches (5 cm) of cool water. Soak for 6 hours at room temperature (70–75°F / 21–24°C). Drain both, reserving a little soaking water to help with grinding.

Step 2: Grind the dosa batter until smooth and airy

In a blender (or wet grinder), grind the urad dal + fenugreek first with 1/2 cup (120 ml) water (use soaking water if you like), adding 1–2 tbsp more as needed. Blend until very smooth, pale, and fluffy, about 3–5 minutes depending on your machine.

Transfer to a large mixing bowl (leave plenty of headspace for rising).

Next, grind the rice with 1/2 cup (120 ml) water, adding more as needed, until smooth to very slightly gritty (like fine semolina), about 3–5 minutes. Stir the rice batter into the urad batter until fully combined.

The mixed batter should be thick but pourable. If it feels like paste, add 2–4 tbsp (30–60 ml) water now.

Step 3: Ferment the batter (the key to flavor and crispness)

Stir 1 1/2 tsp (9 g) kosher salt into the batter. Cover loosely (a lid slightly ajar or a towel) so gases can escape.

Ferment in a warm spot at 80–90°F (27–32°C) for 10–14 hours, until the batter has risen noticeably, looks airy, and smells pleasantly tangy.

After fermenting, gently stir once. Adjust consistency with 1/4 to 3/4 cup (60 to 180 ml) water as needed so the batter pours easily and can be spread thin. Think: a little thinner than pancake batter.

Step 4: Cook the potatoes for the filling

Add the potatoes to a pot and cover with cool water by 1 inch (2.5 cm). Add 1 tsp kosher salt to the water.

Bring to a boil, then reduce to a steady simmer and cook until very tender, 12–15 minutes. Drain well.

Let the potatoes steam-dry in the colander for 5 minutes, then roughly mash (some small chunks are great for texture).

Step 5: Make the spiced potato masala

In a wide skillet over medium heat, heat 1 tbsp (15 ml) oil + 1 tbsp (15 ml) ghee (or all oil). Add 1 tsp mustard seeds and cook until they pop, 30–45 seconds.

Add 1 tsp cumin seeds and 10–12 curry leaves and stir for 15 seconds. Add the sliced onion and cook until soft and lightly golden, 6–8 minutes.

Stir in green chiles and ginger for 30 seconds, then add 1/2 tsp turmeric and optional 1/8 tsp hing.

Add the mashed potatoes, 1/2 tsp kosher salt, and 1/2 cup (120 ml) water. Stir and gently mash to combine. Cook until the mixture is hot and cohesive, 2–3 minutes. Turn off the heat and mix in 2 tbsp lemon juice and 1/4 cup chopped cilantro. Taste and add salt if needed.

Step 6: Blend the coconut chutney and add the tempering

In a blender, combine:

• 1 1/2 cups (120 g) grated coconut
• 2 tbsp (20 g) roasted chana dal
• 1 green chile
• 1/2 inch ginger (5 g)
• 3/4 cup (180 ml) water
• 1/2 tsp kosher salt

Blend until creamy (or slightly coarse, if you prefer), about 30–60 seconds. Add 1–2 tbsp (15–30 ml) extra water if you want a looser, pourable chutney.

For the tempering: heat 2 tsp oil in a small pan over medium heat. Add 1/2 tsp mustard seeds and cook until popping, 30–45 seconds. Add 1 dried red chile, 8 curry leaves, and optional 1/8 tsp hing; stir 10–15 seconds. Immediately pour the hot tempering over the chutney and stir.

Step 7: Cook the sambar (stovetop or pressure cooker)

Stovetop method: Add 3/4 cup toor dal, 3 cups (720 ml) water, and 1/4 tsp turmeric to a pot. Bring to a boil, then reduce to a simmer and cook, partially covered, until very soft, 35–45 minutes. Whisk or mash until creamy.

Pressure cooker / Instant Pot: Cook dal with water and turmeric on High Pressure for 10 minutes, then natural release 10 minutes. Whisk until creamy.

Add vegetables (about 3 cups), shallots/onion, tomato, 2 tbsp sambar powder, 1 tbsp tamarind concentrate, 1 tsp jaggery, and 1 1/2 tsp kosher salt. Simmer until vegetables are tender, 12–15 minutes, adding 1 to 2 cups (240 to 480 ml) water as needed for a stew-like consistency.

Finish with tempering: heat 1 tbsp oil over medium heat. Add 1 tsp mustard seeds and cook until popping, 30–45 seconds. Add 1/2 tsp cumin, optional 1/4 tsp fenugreek seeds, dried red chiles, and curry leaves; stir 15–20 seconds. Pour into the sambar and stir in 2 tbsp cilantro. Taste and adjust salt and tamarind.

Step 8: Cook crisp dosas and assemble

Heat a cast iron skillet/tawa or nonstick skillet over medium-high heat until a few drops of water sizzle and evaporate quickly; target surface temperature is about 400°F / 200°C.

Lightly rub the pan with a few drops of oil on a folded paper towel. Pour 1/2 cup (120 ml) batter into the center and quickly spread in outward spirals with the bottom of the ladle to a thin 10–12 inch (25–30 cm) circle.

Drizzle 1 tsp oil or ghee around the edges and a few drops over the top. Cook until the surface looks set, the edges lift, and the bottom is deep golden and crisp, 2 1/2 to 4 minutes.

For extra crispness, cook 30–60 seconds longer. (No flip is required, but you can flip for 15–30 seconds if you like.)

Spoon about 1/3 cup potato masala onto one side, fold the dosa over, and serve immediately with coconut chutney and hot sambar. Repeat with remaining batter, oiling the pan lightly between dosas as needed.

Pro Tips

• Fermentation cue: The batter should look airy with bubbles and smell pleasantly tangy, not harsh or “off.” If your kitchen is cool, ferment in the oven with the light on (check that it stays around 80–90°F / 27–32°C).
• Batter consistency = spreadability: After fermenting, thin the batter little by little. If it’s too thick, you’ll get pancake-dosas; too thin and it can tear. Aim for “heavy cream” flow.
• Pan heat matters: If the batter sticks, the pan is often too hot or under-seasoned (cast iron). If it turns pale and soft, the pan is too cool. Adjust in small increments.
• Spreading technique: Pour, then spread immediately. If you wait, the batter sets and won’t thin out. One confident spiral is better than many hesitant passes.
• Keep dosas crisp: Serve as you go. If you must hold them, place on a rack in a 200°F / 95°C oven for up to 20 minutes (not covered), but fresh off the pan is best.

Variations

• Mysore-style: Spread 1–2 tsp spicy red chutney (store-bought Mysore chutney or a quick chili-garlic paste) on the dosa before adding the potato filling.
• Cheese masala dosa: Sprinkle 1/4 cup (25 g) shredded cheddar or mozzarella over the dosa right after spreading the filling; fold once melted.
• Extra-veg filling: Add 1 cup (150 g) cooked peas or finely chopped sautéed spinach to the potato masala.

Storage & Make-Ahead

Batter: Refrigerate fermented batter in a covered container for up to 5 days. It will get tangier over time. Stir gently; if thickened, thin with 1–3 tbsp water at a time. For best rise, let it sit at room temperature for 30 minutes before cooking.

Potato masala: Refrigerate up to 3 days. Reheat with a splash of water over medium-low heat until steaming hot, about 6–8 minutes.

Coconut chutney: Refrigerate up to 2 days. Stir before serving; loosen with 1–2 tsp water if needed.

Sambar: Refrigerate up to 4 days. Reheat to a simmer over medium heat (about 6–10 minutes), adding water to loosen.
