Perfect Idlis, Even In Monsoon: Fermentation Tips To Save Your Batter
Chefs and home cooks across regions have a common grievance during the season. Their batter either turns sour too fast, refuses to rise, smells off, or ends up producing flat dosas and dense idlis. Wonder why? As humidity climbs and temperatures fluctuate, the fermentation process becomes unpredictable, leaving even seasoned cooks scratching their heads.
So, what really causes these batter blues during the rainy season? And how can you fix it using simple kitchen techniques and expert-backed tips? Let's break it down.

What Is Going Wrong With Your Batter? The Monsoon Fermentation Puzzle
Fermentation is an essential step towards a wholesome dosa or idli meal. It is not only about how well it rises; fermentation is also about how well the batter develops taste, texture, and digestibility. Nutritionist Amita Gadre explains that fermented batter contains friendly bacteria, but they don't survive cooking temperatures. So, while your dosas and idlis are not probiotic, the batter is still easier to digest due to the breakdown of starch and proteins.

Monsoon tends to throw a spanner in the works. During this time, the weather shifts dramatically and so does the behaviour of your batter. Here's why:
1. Increased Humidity:
It promotes microbial growth, including fungi and bad bacteria, which can spoil the batter or make it overly sour.
2. Cooler Ambient Temperature:
It slows down fermentation by reducing the activity of Lactobacilli (good bacteria).
3. Poor Air Circulation Indoors:
This limits oxygen exchange, which is essential for proper fermentation.

Signs That Your Batter Is Struggling:
1. No visible rise or bubbles after 10-12 hours:
Normally, a well-fermented batter should double in volume and show tiny air bubbles.
2. Excessively sour smell, even in under 8 hours:
A sharp, vinegary smell means the batter has over-fermented or been contaminated by unwanted bacteria.
3. Watery or slimy texture:
This is a red flag. Sliminess often indicates bacterial spoilage or fungal contamination.
4. Idlis coming out flat and dense; dosas turning chewy:
This points to under-fermentation or poor aeration.
5. Discoloration or surface patches:
Grey or green patches suggest fungal growth or oxidation.

Monsoon-Proof Your Batter: Tried-And-Tested Tips
1. Use lukewarm water for grinding:
Cold water slows microbial activity. Use slightly warm water while grinding rice and urad dal to help activate natural fermentation faster.
2. Add natural fermentation boosters:
Soaked poha, a few fenugreek seeds, or a spoon of thick curd can introduce natural bacteria and aid fermentation. These ingredients also improve batter texture.
3. Create a warm microclimate indoors:
Fermentation needs warmth. Wrap the vessel in a thick cloth, place it near a warm appliance, or keep it in a switched-off oven with the light on. Avoid metal surfaces and cold corners.
4. Time it right:
Fermentation may happen more quickly in humid weather. Check the batter after 6-8 hours and refrigerate it as soon as it rises. Leaving it out longer may lead to sourness or spoilage.
5. Always use a lid, but not airtight:
Cover your vessel loosely. A tightly sealed container can trap unwanted gases and moisture, while an open one risks airborne contamination.
6. Refrigerate just after fermentation:
Once the batter is fermented, transfer it to the fridge. This stalls further microbial activity and keeps the taste consistent for up to 2 days.
7. Make smaller batches:
Avoid storing batter for multiple days during monsoon. Prepare just enough for 1-2 meals. This minimizes the risk of spoilage and helps you monitor the fermentation cycle better.

Understanding India's nutritional adequacy
Jul 03, 2025 08:34 PM IST Nutritional adequacy underpins an economy's growth to a significant extent. In this context, the latest Household Consumption Expenditure Survey provides data on nutritional intake that should prompt policymakers to bridge gaps. Despite a shrinking gap between the top and bottom fractiles over the past decade, problems of access, nutrient balancing, efficient targeting and delivery need urgent solutions (HT Photo) First, the calorie consumption at the lowest fractile of India's economic classes (the bottom 5% of the population by expenditure) remains significantly below what is considered ideal for Indian adults. At 1,688 kilocalories (kCal) a day in rural areas and 1,696 kCal in urban areas, the average intake falls short of the recommended daily intake of 2,500 kCal by close to a third. Even as governments — both the Centre and the states — try to ensure adequate intake through support programmes including the public distribution system, several other factors are in play. Problems of access, nutrient balancing, efficient targeting and delivery need urgent solutions. That said, the trend of a shrinking gap between the top and bottom fractiles over the past decade is heartening. Second, the recent trend of diversification of households' nutritional basket holds strong. Though cereals continue to be the single-largest source of protein for households, their share in the overall protein pie is falling, with households turning to pulses, dairy and meat/fish/poultry. That is welcome, given it indicates rising spending on nutritional balance — with commensurate imprints on human health. As non-communicable diseases start to define India's morbidity picture, it is necessary to get the nutritional mix and diet basket right. Third, as the data is parsed for regional patterns, a more comprehensive picture of deficits is likely to emerge, not always fitting neatly with economic conditions. There will be sociocultural factors at play that need to be understood and factored in as the State moves to tweak policies. Unlock a world of Benefits with HT!

Can drinking Jamun-Karela Juice reverse diabetes? How to make it at home
Jamun (Indian blackberry) and karela (bitter gourd) are two traditional ingredients widely used in Ayurvedic medicine for managing blood sugar levels. When combined as a juice, they form a powerful drink believed to help control diabetes. Both are rich in bioactive compounds that target blood glucose regulation, but can they actually reverse diabetes? How Jamun Helps in Diabetes Control Jamun contains jamboline and jambosine, alkaloids that help regulate the conversion of starch into sugar and improve insulin activity. A 2010 study in the Asian Pacific Journal of Tropical Biomedicine highlighted the anti-diabetic potential of Jamun seeds in lowering blood glucose and oxidative stress in diabetic rats. Its low glycemic index and natural astringent quality further support its traditional use in managing type 2 diabetes. Bitter Gourd's Blood Sugar Benefits Karela is a proven natural hypoglycemic agent. It contains compounds like charantin, vicine, and polypeptide-p, which mimic insulin and help lower blood sugar levels. A 2011 study published in the Journal of Ethnopharmacology confirmed karela's effectiveness in reducing fasting blood glucose in type 2 diabetic patients. The juice of karela is often consumed to support insulin sensitivity and reduce glucose absorption in the intestines. Can This Juice Reverse Diabetes? While Jamun-Karela juice can significantly help manage blood sugar levels, there is no conclusive evidence that it can reverse diabetes, especially type 2 diabetes. Reversal requires a comprehensive lifestyle change—diet, exercise, weight management, and sometimes medication. This juice can be a valuable addition to such a regimen but not a standalone cure. Studies support improvement in glycemic control, not complete reversal. Clinical Support and Cautions Clinical trials are ongoing, but available evidence supports the juice as a complementary therapy. A small 2018 study in Ayurveda Journal of Health showed reduced blood glucose and HbA1c levels after 3 months of daily Jamun-Karela juice intake. However, patients must be cautious. Overconsumption can lead to hypoglycemia, especially when combined with diabetic medications. Jamun's slightly sour taste makes it a cooling choice during the rains. It helps digestion, cuts down acidity, and soothes mild bloating. According to a study published in the National Library of Medicine, its antioxidants and bioactive compounds calm the gut and support overall metabolic balance. How to make this juice To make Karela Jamun juice at home, wash and chop 2 medium-sized bitter gourds (karela), removing the seeds, and soak the pieces in salted water for 15 minutes to reduce bitterness. Wash and deseed about 10–12 fresh jamuns or use 2 tablespoons of jamun pulp or powder. Blend the karela and jamun with 1 to 1½ cups of water until smooth, then strain the juice using a fine sieve. Optionally, add a pinch of black salt and a few drops of lemon juice for taste. Drink fresh on an empty stomach in the morning, and store any leftovers in the fridge for up to 24 hours.
