Method
Season the mushroom chunks with the salt and light soy sauce and leave to marinate for 10 minutes.
Whisk the plain flour, half the cornflour and the ice-cold water into a thick batter, then coat each mushroom chunk.
Heat the vegetable oil in a wok to 180°C and deep-fry the mushrooms in batches for 4 minutes until golden and crisp, then drain.
Pour off most of the oil, leaving about 1 tablespoon in the wok, and stir-fry the onion, red pepper and green pepper for 3 minutes until just softened.
Add the pineapple and stir-fry for 1 minute.
Stir the ketchup, rice vinegar and sugar together in a small bowl, then pour into the wok and bring to a simmer.
Mix the remaining cornflour with a little cold water, stir into the sauce, and cook for 2 minutes until it thickens and turns glossy.
Toss the fried mushrooms through the sauce until every piece is coated, then serve immediately.
