Tips for Quick Fermentation in Winters

idli-fermentation-winters

Hot steamy sambhar and fluffy idli are marvellous quick fix for chilly mornings. Fermentation makes food light on tummy and make food easily digestible. We make idli batter a night before, grind pulses and rice night before and let it ferment overnight. Perfect fermentation is essential for perfect fluffy idlis. Fermentation takes less time when the weather is hot (7-8 hours). But in winter season, fermentation takes longer and keeping overnight is not sufficient. So, here the tips to make perfect idli batter with quick fermentation in cooler season. The main difference of temperature exists in winter, other tips should be followed in all seasons.

Hope it will work for u.😊

Upon searching for uses of fermentation I came across an article and was so overwhelmed by nutritional benefits of fermentation. I am bound to share the facts and figures with you. This increased volume of idli batter is due to the incorporation of lactic acid bacteria into the batter during fermentation and entrapment of air.

During fermentation, maximum production of riboflavin and thiamine were found to be 0.76 mg/100 gm and 0.73 mg/100 gm in 3:1 blend ratio of idli batter; and the folic acid content was found to be at a maximum of 0.75 mg/100 gm of idli batter after 10 h of fermentation. Those who want to go deeper into the whole process of idli making including fermentation can soon look for a separate post. 😊

Tips For Perfect Fermentation

👉 Select Perfect Ingredients

Do not use contaminated or old to rice and daal. Parboiled rice or Idli rice works best. Split urad daal with husk is best. Avoid dehusked and split urad daal. Black whole urad dal is not good for making idlies.

👉 Correct Soaking

I keep ratio of rice and urad daal (3:1). Soak rice and daal separately as well as grind separately too. 

We usually make this mistake quite often to save time. However, grinding rice and Dal separately not only increases volume and but also aids in fermentation.

Wash rice and drain the water. Soak the rice in water overnight (preferably 8 hours / at aleast 4 hours). Soak urad Dal after washing and draining  water to one hour before you start to grind the batter to give volume to the batter when ground.

  • Addition of fenugreek seeds (Methi) You can soak Methi seeds (1.5 tsp) while soaking daal. Fenugreek seeds helps to aid fermentation.
  • Adding poha (flattened rice) or cooked rice, while grinding also helps for quick fermentation.
  • Sabudana too aids in fermentation by helping good bacteria do its work more efficiently. 
  •  Grind rice to a coarse paste  such that you should feel the tiny granules. Do not grind the rice to a smooth batter. 

👉 Use Filtered Water while Grinding

Avoid using chlorinated water  for grinding. Instead use filtered water. Chlorine and fluorine inhibits growth of wild yeast which is essential for fermentation. 

👉 Add Salt in Batter before Fermentation

At times, not adding enough salt to the batter after its ground can also be a reason for lack of fermentation. Add 1 tsp  for every 1 cup of dry ingredients for idli. Use non-iodized salt or rock Salt (minimally processed). Ordinary Table salt contains other ingredients such as anti-caking agents etc… which may interfere in fermentation.

Acceptable level of fermentation is when the batter has doubled in volume

👉 Maintain Warm Temperature

Ideal temperature  for fermentation ranges from 25 to 28 °C (77 – 82.4 °F). In case of lower temperature, try remedies to increase temperature.

  • Immerse the vessel containing the batter in a container of warm water.
  • Turn on the light in the oven, and use that to keep the batter warm or pre heated oven  in 90c for 10 minutes and switch off the oven. 
  • You can also wrap a blanket around the container containing better to keep it warmer.
  • Keep the container in warm place  of your house. If you use a room heater, placing the vessel in that room would help in fermentation.

👉 Correct Consistency of Batter

Maintaining a correct consistency of Idli batter is important as too little and too much water can retard the process of fermentation it is recommended that makes the better using your hands and makes them thoroughly as uneven mixing may retard the process of fermentation. Try to mix the batter using ur hands, your body heat would boost fermentation. Your grinded batter should have the consistency of ketchup, flowy, smooth and velvety in texture.

Do not keep batter in air tight container or lid. Instead simply loosely cover it with a plate.

👉Avoid Adding Fermentation Retarders

Baking soda, Baking powder and Yogurt may hinder process of fermentation by inhibits growth of wild yeast. You can add 1/4 tsp of baking soda or baking powder to the fermented batter. Also, adding 1/2 tsp of ENO plain fruit salt for 1 cups of idli batter makes the idli soft even if its not fermented well.

👉 Last Resort

  • Try adding a fermentation starter like a spoonful of commercially prepared idli batter as they have live culture, it helps for fermentation.
  • Add Half tsp of yeast in half cup water and a teaspoon of sugar and then add it to a gallon of batter.
