Prepare the chicken coating. Whisk the egg white and 75g cornflour together until combined. Season with salt and pepper, then add the chicken and toss until every piece is evenly coated.
Mix the sauce. In a separate bowl, whisk together the sweet chilli sauce, soy sauce, water, lime juice and 4 teaspoons cornflour. Set aside.
Fry the chicken. Heat the vegetable oil in a large frying pan over medium-high heat. Fry the chicken in batches until golden and cooked through. Transfer to a plate lined with kitchen paper to drain.
Prepare the pan. Carefully pour off the excess oil, leaving about 2 tablespoons in the pan. Add the ginger and garlic and cook briefly until fragrant.
Add the chilli. Stir in the sliced red chilli and cook for a few seconds, taking care not to burn the garlic.
Add the honey. Pour in the honey and stir to combine it with the garlic, ginger and chilli.
Make the glaze. Give the prepared sauce mixture another stir, then pour it into the pan. Bring to a gentle simmer, stirring regularly, until the sauce thickens and becomes glossy.
Coat the chicken. Return the cooked chicken to the pan and toss until every piece is coated in the sticky glaze. Serve immediately, topped with sliced spring onions and chopped coriander.
