Wet grinding is the hardest job for a mixer grinder in an Indian kitchen. Turning soaked urad dal and rice into smooth, aerated batter keeps the motor under heavy load for several minutes at a time, far longer than blending lassi or grinding dry spices.
Most 750W+ mixers can do it. The questions are how quickly, and how long the motor can keep going before it needs a rest.
Every model below is one we list: rated 4★ or higher on Amazon, with at least 100 ratings and an Amazon "bought in the past month" badge (late September 2026). Picks are based on each model's listing and Amazon ratings; we haven't run hands-on tests.
The 3 Things That Decide Wet-Grinding Performance
1. Rated Running Time (Not Just Wattage)
Check how long the brand says the motor can run. Sujata rates its 900W and 1000W models for 90 minutes of continuous running; Philips quotes 25 minutes for the HL7756; Bosch rates its 1000W models for 5 minutes on, 2 minutes off (30 minutes in total). For big batches of batter, a longer rating means fewer forced pauses.
2. Jar Design — Flow Breakers
Good wet-grinding jars have flow breakers: ridges on the inside wall that stop batter spinning round with the blade and push it back into it. Crompton, Maharaja Whiteline and others call this out on their listings.
3. Motor Power
More wattage grinds a full jar faster. 750W is comfortable for regular batter; 900–1000W helps with large or frequent batches.

Wet Grinding Tips for Indian Kitchens
1. Always soak ingredients adequately Urad dal for idli: 4–6 hours. Rice for dosa: 4–6 hours. Insufficient soaking forces the motor to work harder and generate more heat.
2. Grind in batches For 500g+ of batter, grind in 2–3 batches of 5–7 minutes each with 2-minute breaks. Continuous grinding for 20+ minutes without breaks stresses even the best motors.
3. Add water gradually Start with minimal water, add gradually as the batter thickens. Starting with too much water creates a sloshing liquid that doesn't grind properly.
4. Use the right jar for the quantity For small batches, the 1L multipurpose jar grinds batter more evenly; for larger batches use the wet or liquidising jar, and don't fill it more than about two-thirds.
5. Clean immediately after use Dried dosa batter is extremely hard to clean. Fill the jar with warm water + 1 drop soap → run for 10 seconds → rinse. Takes 30 seconds. Waiting until the next day means scrubbing for 5 minutes.
Wet Grinding Tips for Perfect Idli Batter
Idli batter is more demanding than dosa batter because idlis require a highly aerated, fermented batter to achieve their characteristic soft, spongy texture. The grinding stage is critical.
Soaking Time
- Urad dal (split black gram): Soak for 6–8 hours (or overnight). Undersoaked dal produces dense, chewy idlis. The dal should be visibly swollen and soft before grinding.
- Idli rice (parboiled rice): Soak for 4–6 hours. Regular raw rice can be soaked for 2–3 hours, but parboiled rice needs longer.
- Fenugreek seeds (methi): Add 1 teaspoon to the urad dal while soaking. Fenugreek aids fermentation and gives idlis their slight tang.
Water Temperature
This is where most people go wrong. Use cold water — preferably refrigerator-cold water — when grinding. Cold water prevents the motor's heat from warming the batter during grinding. Warm batter ferments unevenly and can over-ferment, producing overly sour idlis. Some households in Chennai and Bengaluru add ice cubes directly to the batter during grinding on hot days.
Water Ratio
For 2 cups urad dal: add water very gradually. Start with ¼ cup, let the grinder incorporate it, then add more in small additions. The final batter should be thick and fluffy — it should fall from a spoon in a thick ribbon, not run like a liquid. Over-watering during grinding produces flat, dense idlis.
Grinding Sequence
Always grind urad dal first, separately, before adding rice. Urad dal needs 15–20 minutes of dedicated grinding to become light, airy, and white. This aeration is what makes idlis spongy. Then grind the soaked rice separately to a slightly coarser consistency and mix both batters together by hand (not in the mixer — you want to preserve the air incorporated during grinding).
How Long Should You Grind Dosa Batter?
The most common mistake with dosa batter in a mixer grinder is either under-grinding (coarse batter) or over-grinding (batter heats up, kills fermentation). Here's a practical timing guide:
For 750W Mixer Grinder (2–4 servings)
| Phase | Duration | What to Look For |
|---|---|---|
| Urad dal grinding (first batch) | 5–7 min | Batter turns white, thick, airy |
| 2-minute rest | 2 min | Let motor cool |
| Urad dal grinding (second batch) | 5–7 min | Smooth, no visible granules |
| Rice grinding | 5–8 min | Slightly grainy texture is fine |
| Total active grinding time | 15–22 min | Smooth, spreadable consistency |
For 900W+ Mixer Grinder (4–6 servings)
| Phase | Duration | What to Look For |
|---|---|---|
| Urad dal grinding | 8–10 min (one batch) | White, fluffy, airy |
| 2-minute rest | 2 min | Mandatory even with 900W |
| Rice grinding | 6–8 min | Semi-smooth |
| Total active grinding time | 16–20 min | Ready for fermentation |
Signs the batter is ready:
- Urad dal batter: white, thick, and when you drop a small ball into water, it floats
- Rice batter: no visible rice granules when rubbed between fingers
- Combined batter: flows slowly from a ladle, not watery
Signs of over-grinding:
- Batter feels warm (above body temperature)
- Batter turns slightly grey or off-white
- Idlis from over-ground batter are flat and slightly gummy
What Causes Grainy Idli Batter — And How to Fix It
Grainy idli batter is one of the most common complaints from households that have switched from a traditional wet grinder to a mixer grinder. Here's a systematic diagnosis:
Cause 1: Insufficient Soaking
Symptom: Batter is grainy despite long grinding. Urad dal visible as small specks. Fix: Extend soaking time. If dal isn't softened enough to press flat between fingers, it needs more soaking. In winter, soak urad dal for up to 10–12 hours.
Cause 2: Motor Overheating Mid-Grind
Symptom: Grinding was fine for 5 minutes, then the batter becomes progressively coarser as the motor slows under heat. Fix: Grind in shorter batches — never more than 5 minutes per batch for budget mixers. Add cold water between batches to bring batter temperature down.
Cause 3: Wrong Jar
Symptom: Batter is grainy despite adequate soaking and grinding time. Fix: Switch to the multipurpose 1L jar with flow breakers, not the large liquidising jar. The wide liquidising jar creates a vortex that doesn't pull batter into the blade effectively for wet grinding.
Cause 4: Too Much Batter for the Jar Capacity
Symptom: Bottom of jar grinds fine but top portion stays coarse. Fix: Fill the jar to no more than 60% capacity. For a 1L jar, that's 600ml of batter. Grind in two batches instead of one.
Cause 5: Underpowered Motor
Symptom: Even with correct technique, batter never gets smooth. Fix: If your mixer is below 750W, it may simply not have enough power for proper wet grinding. Upgrade to a 750W minimum. For large or frequent batches, a 900–1000W motor rated for long running, like the Sujata Dynamix, makes it easier.

Frequently Asked Questions
Which mixer grinder is best for dosa batter in India? The Sujata Dynamix 900W: a double ball-bearing motor rated for 90 minutes of continuous running and 4.5★ from over 14,000 ratings. The Sujata Supermix has the same motor rating for about ₹800 less; the Bosch Pro 1000W adds hands-free lid locks.
Can a 500W mixer grinder make dosa batter? Yes, in small batches with rest breaks. If you grind batter more than a couple of times a week, a 750W–1000W model is quicker and copes better with full jars.
How long should I grind dosa batter in a mixer grinder? In batches of a few minutes with short breaks, grinding the urad dal first for maximum aeration. Follow your mixer's rated running time.
Mixer grinder vs wet grinder — which is better for dosa batter? A table-top stone wet grinder grinds slowly without heating the batter, and many cooks find it gives fluffier idlis. A good mixer grinder makes very good batter for most households and does everything else too. If you make batter daily for a large family, a wet grinder is worth considering.
Why are my idlis coming out flat even with a good mixer grinder? Usually one of three things: (1) the batter warmed up during grinding, which affects fermentation; (2) the urad dal wasn't ground long enough to aerate; or (3) too much water was added. Use cold water and grind the dal in its own batches.
