Mix rice flour, arrowroot (or cornflour), Tang Sichuan in a bowl
Heat oil in a wok until it’s hot – this happens once a little flour sizzles in the oil
Line a tray with paper towels
Dip each piece of squid into flour mix, swirl around with fingertips to make sure all is coated, shake off excess flour then place squid into the hot oil
Cook for only 1 minute or so but no longer – otherwise it will be tough and rubbery
Remove and drain on paper towels.
Note: Cook the squid in batches and do not over-crowdthe wok.
