If you are looking for a tawa to help you cook healthy food, any of the above products would be a good choice. An iron or cast iron tawa is usually a good choice, as iron is safe for health and minimal amounts of iron residues are beneficial. However, a tawa with a high-quality and food-grade non-stick layer would be a great option too. The non-stick layer reduces the amount of oil you need while cooking parathas or other dishes.
