Idli & Idli Batter Guide – How to Make Soft Idlies in European Kitchens

Soft steamed idlies served traditionally

What Makes Idli Soft?

Soft idlies depend on correct rice selection, properly aerated urad dal and controlled fermentation. Idli batter must trap air during grinding and fermentation to produce a light, fluffy texture after steaming.

Choosing the Right Rice for Idli

Traditional idli uses parboiled medium-grain rice. For best results, use Idli Rice, which is processed specifically for fermentation. Basmati rice is not suitable as it produces dry and crumbly idlies.

The Ideal Idli Batter Ratio

  • 3 cups idli rice
  • 1 cup urad dal
  • 1 teaspoon fenugreek seeds (optional)
  • Salt added after fermentation

Printable Idli Batter Ratio Guide

Preparation Type Rice Urad Dal Notes
Standard Idli 3 cups 1 cup Balanced softness & structure
Softer Idli 2.5 cups 1 cup Higher aeration
Thatte Idli 3 cups 1 cup Slightly thicker batter
Idli & Dosa Batter 3 cups 1 cup Thin slightly for dosa use

Step-by-Step Preparation

Step 1: Soaking

Wash rice and dal separately. Soak for 4–6 hours. In colder European climates, slightly warm water (not hot) may assist later fermentation.

Step 2: Grinding

Grind urad dal until fluffy and airy. Grind rice separately to a slightly coarse texture. Combine both and mix thoroughly by hand.

Step 3: Fermentation

Fermentation ideally occurs between 25–32°C. Natural bacteria convert sugars into gas, causing the batter to rise.

Fermentation Temperature Quick Reference

Room Temperature Fermentation Time Recommendation
30°C 6–8 hours Normal fermentation
25°C 8–10 hours Ideal range
20°C 10–14 hours Use oven light method
Below 18°C 14+ hours Wrap container & provide warmth

How to Ferment Idli Batter in Cold European Weather

  • Place batter in a switched-off oven with light on.
  • Wrap container in a thick towel.
  • Keep near (not on) a radiator.
  • Allow 8–14 hours depending on temperature.

Signs of Proper Fermentation

  • Batter volume increases
  • Surface appears airy
  • Mild sour aroma develops

Common Problems & Solutions

Idlies Are Dense

Urad dal not ground fluffy enough or fermentation incomplete.

Batter Did Not Rise

Temperature too low. Extend fermentation time.

Idlies Are Sticky

Rice ground too fine. Maintain slight grain texture.

Too Sour

Fermentation too long. Refrigerate once risen.

Steaming the Idlies

Grease moulds lightly. Steam 10–12 minutes. Allow to rest before removing.

Thatte Idli Variation

Use flat moulds and steam slightly longer (12–14 minutes) for thicker idlies.

Using Ready-Made Batter

Bring batter to room temperature before steaming. Stir gently to preserve aeration.

Frequently Asked Questions

Why are my idlies not soft?

Usually due to incomplete fermentation or insufficiently fluffy urad dal grinding.

Can I ferment idli batter in winter?

Yes. Use oven-light method or insulated wrapping.

How long does idli batter ferment in Europe?

Between 8 and 14 hours depending on temperature.

Can I use basmati rice for idli?

No. Basmati does not produce the correct texture.

What is the difference between idli and dosa batter?

The base ratio is similar, but dosa batter is thinned before cooking.
