Tragic Loss in Ahmedabad
A harrowing event unfolded in Ahmedabad where two young girls succumbed to severe vomiting after eating dosa prepared with readily available, store-bought
fermented batter. Their parents also fell critically ill, underscoring the severity of the suspected food poisoning. Authorities have since collected samples of the batter from the vendor for thorough investigation by the Food and Security Laboratory (FSL), seeking to pinpoint the exact cause of this devastating outcome. This incident brings into sharp focus the potential health hazards lurking in convenience food items, especially those involving fermentation processes that require careful handling and storage.
Understanding 'Khiru' Batter
Khiru, a traditional fermented batter prevalent in Gujarati cuisine, is the cornerstone for beloved South Indian dishes such as dosa, idli, and uttapam. Its creation involves a meticulous blend of rice and skinless urad dal, which is then left to ferment for a period ranging from 4 to 5 hours up to overnight. This crucial fermentation stage is what imparts a desirable light, airy texture essential for achieving perfectly fluffy and delicious results in these culinary staples. The process itself is an age-old technique embraced in Indian kitchens for its contribution to digestibility and flavor, but its efficacy is highly dependent on precise execution and hygiene.
Risks of Store-Bought Batter
Experts strongly advise heightened caution regarding store-bought fermented batters, especially during warmer months when the risk of spoilage and bacterial proliferation escalates significantly. Such products, often exposed to the elements and handled by multiple individuals, can become breeding grounds for harmful microorganisms if not maintained under strict refrigeration. Over-fermentation, a common issue exacerbated by heat, can render the batter excessively sour, leading to digestive distress like acidity and bloating. Furthermore, the presence of undisclosed preservatives or stabilizers in packaged batters can pose long-term health concerns. Unhygienic handling practices, contamination from unwashed ingredients like polished rice and dal, and improper whisking techniques further amplify the risks, potentially causing severe gut issues and discomfort.
Home Preparation Safety
Preparing fermented batters like khiru at home offers greater control over hygiene and ingredient quality. A recommended method involves soaking 1 cup of rice and 1/4 cup of urad dal with 1-2 tbsp of poha and 1/2 tsp fenugreek seeds for 4-6 hours. The urad dal and fenugreek should be ground until light and fluffy, while the rice should be ground to a slightly coarse consistency. Combine these, add salt to taste, cover, and let it ferment in a warm place for 8-12 hours. Crucially, avoid adding salt to the entire batch; instead, season only the portion intended for immediate use, refrigerating the rest to slow down spoilage. It is also advisable to allow natural fermentation and refrain from using baking soda, as chemical additives can interfere with gut health and increase the risk of adverse reactions.
