Your non-stick pan is lying to you.
Modern non-stick coatings degrade with every use. They release microplastics into your food. They last 3 years if you are lucky, then end up in a landfill.
Cast iron does none of that. It gets better with use. The more you cook, the more non-stick it becomes. No coating to chip. No chemicals to leach. Just iron.
Your grandmother knew this. Ironster brings it back — pre-seasoned and ready for today's Indian kitchen, made with pride in Kolhapur, Maharashtra.
