Recipe video above. It only took us 3 years to crack the ultimate, truly crispy Salt and Pepper Squid! Hand on heart, this is crispier than any squid I've had in a restaurant, ever. The fry batter is light, super crunchy and not greasy at all. In fact, it's so crispy it stays crispy even when it's stone cold!After eliminating rice flour, potato flour and tapioca, we found the perfect ratio of flour to cornflour (cornstarch) that fries up crunchy in mere minutes, before the squid can overcook. But the final key was refrigerating the batter for 30 minutes. This allowed the gluten to develop so the batter clings to the slippery squid better and doesn't fry up chewy or greasy.
