If your nuts are still sticky, then these haven't quite cooked long enough - you can return them to the pan and to heat until they begin to develop a grainy crust (crystallised texture). Alternatively, the sticky nuts can be used as they are for topping ice cream or other desserts. They won't be crisp and they also won't keep quite as well for as long as the fully candied version. Dependent on what you're using them for, these may still work great!
