Using a non-stick tawa (also known as a griddle or flat pan) after the non-stick coating has come off is not recommended. Once the non-stick coating starts to wear off, the surface becomes uneven, rough, and potentially unsafe for cooking.
Here are a few reasons why you should avoid using a non-stick tawa with a worn-off coating:
Food sticking and uneven cooking: Without the non-stick coating, the surface of the tawa becomes rough and uneven. This can cause the dough to stick to the surface, leading to difficulty in flipping and cooking roti evenly.
Health concerns: Non-stick coatings often contain chemicals like polytetrafluoroethylene (PTFE) or perfluorooctanoic acid (PFOA), which can be harmful if ingested. When the coating starts to wear off, there is a risk of these chemicals leaching into your food.
Possible damage to the tawa: Cooking on a tawa with a worn-off non-stick coating can cause further damage to the pan. The rough surface can be difficult to clean and may also promote rusting.
Instead of using a non-stick tawa with a damaged coating, consider investing in a new tawa or using an alternative like a cast-iron or stainless steel tawa. Both cast-iron and stainless steel tawas are safe options for making roti and other flatbreads. While these surfaces may require a bit of oil or ghee to prevent sticking, they provide excellent heat distribution and can last for a long time with proper care.
Remember to season your cast-iron tawa properly before using it for the first time to enhance its non-stick properties. Additionally, always follow the manufacturer's instructions for cleaning and maintenance to ensure the longevity and performance of your cooking surface.
