Yes, jaggery syrup should be sealed with muslin cloth while cooling to prevent impurities and crystallization. This ensures a smooth and clear syrup.
When preparing jaggery syrup, it's crucial to maintain its purity and prevent unwanted crystallization. Jaggery often contains small particles of dirt or impurities from the manufacturing process. Sealing the cooling syrup with muslin cloth serves as a natural filter. As the syrup cools, the cloth prevents dust, insects, and other airborne particles from contaminating it. Furthermore, it helps to slow down the cooling process, which is essential for preventing sugar crystals from forming. Rapid cooling can lead to a grainy texture, while slow, controlled cooling under muslin cloth promotes a smooth and consistent syrup. The muslin cloth allows air to circulate while acting as a barrier against contaminants.
Before using the muslin cloth, sterilize it by boiling it in water for a few minutes. This will eliminate any potential bacteria or contaminants that could affect the quality of your jaggery syrup.
