Heat oven to 220C/fan 200C/gas 7. In a
roasting tray, toss the wings with the soy
sauce, 125g of the sugar, 2 tbsp of the vinegar
and some cracked black pepper. Roast for
40 mins, turning occasionally until lacquered.
Meanwhile, bring the remaining sugar and
vinegar to the boil for about 1 min, until the
sugar dissolves. Leave to cool, then toss with
the cucumber ribbons. Serve the sticky wings
with the cucumber and some boiled rice.
