Put the black peppercorns, salt, Sichuan peppercorns, garlic powder and chilli flakes in a pestle and mortar or blender and grind to a fine powder
Heat a pan 1/3 full with sunflower oil to 200C.
Make the batter for the squid by mixing together the cornflour and soda water and stir in about a tablespoon of the seasoning.
Add a little more cornflour to a bowl and coat the squid rings. Dip the coated squid in the batter and then fry in batches, for about 3 minutes, until crisp and beginning to turn golden. Drain on kitchen paper.
Meanwhile, heat a tablespoon of sunflower oil in a frying pan over a medium heat. Add the chillies, spring onions and garlic and fry until softened, around 3 minutes. Once cooked, add the crispy squid and the remaining seasoning and toss to combine. I also like to add a little more sprinkling of chillies flakes at this stage for extra heat.
Once all the squid is cooked, add to the pan with the chillies, spring onions and garlic. Stir in the remaining seasoning and toss to combine. I also like to add a little more sprinkling of chillies flakes at this stage for extra heat.
Serve the Salt and Chilli Squid with some sweet chilli sauce on the side.
