Where It Grows
Idli is a food product that is not grown but prepared and is a staple in the Southern regions of India. The main ingredients needed for Idli preparation are rice and urad dal (black lentils), both of which are widely cultivated in India, particularly in the states of Andhra Pradesh, Tamil Nadu, Karnataka, and Maharashtra. Rice generally requires a hot, humid climate and plenty of water to grow, while urad dal thrives in a tropical climate with a well-drained loamy soil. Additionally, these ingredients are also grown in other Asian countries such as China, Thailand, Vietnam for rice, and Myanmar and Bangladesh for urad dal.
Best Way to Eat
Idlis are best consumed fresh off the steamer as they are soft and fluffy. They are traditionally served with sambar (a lentil soup) and coconut chutney, both of which add to the nutritional value of the meal. Sambar is rich in proteins and fiber due to the lentils and assorted vegetables used in its preparation, while coconut chutney provides healthy fats. Idlis are steamed, which is a healthy cooking method as it doesn't require the use of oil and thus, aids in controlling calorie intake. To maximize the nutrition, one can add vegetables or sprouts to the Idli batter. Fermentation of the batter also enhances the bioavailability of nutrients like B-vitamins and proteins in the food.
