If using Brazil nuts, roughly chop some of them up into halves and quarters to make them more bite size. Place all the nuts onto two large roasting trays, then carefully divide the melted butter and honey mix between the two, then scatter over the paprika. Toss to coat all the nuts, then cook for 20-30 minutes, or until golden all over, carefully shaking the tray every 10-15 minutes to make sure they cook evenly.
