Chef's Tip: Precious cold pressed sesame oil is authentic and essential for this Tamil dish – the sesame flavour is inseparable from traditional prawn thokku. Do not substitute. The natural sesamin in sesame oil also helps preserve the seafood dish.

Cook with authentic cold pressed oils — the difference is in every bite.
