Preheat the oven to 180°C/160°C Fan
Toss the nuts in a large bowl to combine and spread them out on a baking sheet. Toast in the oven till they become light golden-brown, about 10 minutes.
In a large bowl, combine the rosemary, cayenne, muscovado sugar, salt and melted butter.
Thoroughly toss the toasted nuts in the spiced butter and serve warm. And once you eat these, you will never want to stop.
