Meanwhile, heat the oven to 200C/180C fan/gas 6 and line a baking tray with baking parchment. Toss the crumpet chunks with the olive oil in a bowl until well coated. Spread out on the lined tray and bake for 15 mins, turning halfway through, until golden and crisp. Or, air-fry the crumpet chunks at 180C for 8-10 mins, shaking the basket halfway through. Set aside to cool.
