Bhapa ilish. Gorgeous ilish steaks. A slather of piquant mustard. A generous glug of mustard oil. A throw of wicked green chillies. All snugly packed in an old-school stainless steel tiffin-box and steamed to perfection. (and that intoxicating aroma when you prise open the lid of the box. What a delight for the olfactory nerves) this is food heaven
