The secret to a crisp dosa or a fluffy idli is the batter: soaked rice and urad dal ground smooth and airy, then fermented. Grinding it is the hardest job you'll ask of a mixer grinder: a thick, heavy load for several minutes at a time.
Push an underpowered mixer too hard and the motor strains, the jar warms up and the overload switch trips. Warm batter can also ferment less well. So what do you actually need?
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.
1. What Each Wattage Can Handle
500W: fine for chutneys, smoothies and masala, and it can grind batter in small batches with rest breaks. If you make batter often, it will feel slow. The Bajaj Rex 500W is the best-rated budget option.
750W: comfortable for regular batter in normal family quantities. The Philips HL7756 is a well-proven choice, and Philips quotes 25 minutes of continuous grinding.
900–1000W: grinds full jars faster and suits large or daily batches. Several models in this range are also rated for long continuous running.
2. Rated Running Time Matters as Much as Wattage
A powerful motor that has to stop every few minutes is less convenient for big batches than a slightly smaller one rated to keep going. From the listings:
- Sujata Dynamix, Supermix (900W) and MG03 (1000W): 90 minutes of continuous running
- Philips HL7756 (750W): 25 minutes of continuous grinding
- Bosch Pro 1000W: 5 minutes on, 2 minutes off, up to 30 minutes

4. Features to Look For Beyond Wattage
1. Flow breakers: ridges on the inside of the jar push batter back into the blades so rice grains don't escape.
2. Overload protection: a resettable switch that cuts power before the motor overheats.
3. Ventilation: vents in the base help the motor shed heat during long grinds.

Frequently Asked Questions (FAQs)
1. Why does my dosa batter become hot while grinding? Friction from the blades and heat from a working motor. Grind in shorter batches, use chilled water, or add an ice cube while grinding.
2. Can I grind idli batter in a 500W mixer grinder? Yes, in small batches with rest breaks. If you make batter often, a 750W or larger motor is quicker and less likely to trip its overload switch.
3. Is a stone wet grinder better than a mixer grinder? A table-top stone wet grinder works slowly without heating the batter, and many cooks find it gives fluffier idlis. It's also bulkier and takes longer. A good 750W+ mixer grinder makes very good batter for most families and handles everything else too.
4. What is the ratio of rice to urad dal for dosa? A common ratio for crisp dosas is 3:1 (3 cups of idli or raw rice to 1 cup of whole white urad dal), with a teaspoon of fenugreek (methi) seeds to help fermentation.
5. How long should I run the mixer continuously? Follow your model's rating: Sujata's 900W models are rated for 90 minutes, Philips quotes 25 minutes for the HL7756, and Bosch rates its 1000W models for 5 minutes on, 2 off. Short bursts with a pause to scrape down the sides also give a smoother batter.
