Sweet and sour chicken is the takeaway order that never goes out of style. This quick version skips the batter and deep fryer: the chicken gets a light cornflour coating and a hot pan, so it's golden and tender in minutes.
The sauce is classic pantry: tomato ketchup, rice vinegar, sugar, soy sauce and pineapple juice from the tin, thickened with cornflour until glossy.
Serve over steamed rice for a weeknight fakeaway.
