Classic Idli (3 Pcs) Recipe

Soak rice, dal and poha

Rinse the rice in several changes of water until the runoff is nearly clear. Rinse the urad dal separately until clear. In separate bowls, combine the rinsed rice with the poha and cover with enough water to soak (about 1 to 1 1/4 cups). Cover the urad dal with about 3/4 to 1 cup water. Soak both bowls for 4 to 6 hours at room temperature (or 2–3 hours in a warm place).

Drain and reserve soaking water

After soaking, drain both rice+poha and urad dal. Reserve the soaking water for later; you will use measured portions to help achieve proper batter consistency while grinding.

Grind urad dal

Transfer the soaked urad dal to a wet grinder or high-speed blender. Add about 3 to 4 tablespoons of the reserved soaking water (or fresh water if needed). Grind to a smooth, fluffy, and slightly airy batter — it should be light and soft, not watery. This typically takes 15–25 minutes in a wet grinder, or 6–10 minutes in a powerful blender, pausing to scrape as needed.

Grind rice and poha

Grind the soaked rice and poha with about 1/2 to 3/4 cup of the reserved soaking water (use smaller amounts first) to a slightly gritty but cohesive batter; the texture should be finer than coarse semolina but not as silky as the urad batter. Total grinding time about 8–12 minutes in a wet grinder or 4–6 minutes in a blender, in short pulses, scraping the sides to ensure even grind.

Combine batters

Transfer both batters to a large bowl (preferably deep for rising). Mix the urad dal batter and rice batter thoroughly by folding and beating gently with your hand or a spatula to incorporate air — this helps fermentation. Add salt and mix again until combined. Adjust consistency with reserved water: the combined batter should be thick but pourable, similar to pancake batter (for 2 cups total dry ingredients, about 2 to 2 1/4 cups water total is typical).

Ferment batter

Cover the bowl with a lid or cloth. Leave in a warm place (78–95°F / 26–35°C) for 8–12 hours or overnight until the batter rises and becomes airy with small bubbles. In cooler climates, fermentation can take 12–18 hours; you can place the bowl in an oven with just the light on or on a heating mat. After fermentation, gently stir the batter once — do not overmix and deflate completely.

Prepare steamer and molds

Add about 1 cup of water to a steamer, idli cooker, or pressure cooker (without the weight/whistle). Bring the water to a vigorous simmer over medium-high heat. Lightly grease three idli molds (single-serving mold that makes 3 idlis) or idli plates with the oil or ghee using a brush or your fingertip.

Fill molds

Stir the fermented batter once gently. Spoon batter into each molded cavity filling about three-quarters full to allow expansion. Smooth top lightly with the back of the spoon.

Steam idlis

Carefully place the idli stand/plate into the steamer. Cover and steam on high steam for 10–12 minutes for standard idlis made from 3/4–1 inch cavities; larger molds may take 12–15 minutes. Do not lift the lid while steaming to preserve steam. To test doneness, insert a toothpick into the center of an idli — it should come out clean. If using an electric steamer, follow manufacturer timings but generally 10–14 minutes.

Remove and cool

Turn off the heat and let the idlis sit covered for 2 minutes. Remove the lid, then use a spoon or thin knife to loosen the edges and gently scoop out each idli onto a plate. Allow to cool for 1–2 minutes so they set slightly; they will be soft and fluffy.

Serve

Serve idlis warm with chutney (coconut chutney, tomato chutney) and sambar. Leftover idlis can be refrigerated for up to 2 days and reheated by steaming for a few minutes or microwaving with a damp paper towel to retain moisture.
