Preheat the over to 350 F (175 C).
Then line two baking sheets with baking paper.
In a large mixing bowl, combine the nuts and add the pink Himalayan Salt, white pepper and cayenne pepper.
In a saucepan on medium heat, combine the sugar, water and butter. Heat through and cook for around 1 minute without boiling.
Pour the heated sugar mixture into the bowl of nuts and stir gently to coat the nuts and mix through the salt and peppers.
Next, transfer the nut mixture to the prepared baking sheets. Aim to spread the nuts out into a single layer.
In the preheated oven, bake the nuts for 8 minutes before removing them to give them a stir. Ensure the nuts are well coated with the sweet and spicy syrup. Then transfer the baking sheets back into the oven for a further 8 minutes, or until the nuts are sticky and well roasted.
Once the nuts have cooled, seperate the nuts with a spoon or clean hands. The spicy sugar coating will harden once completly cooled.
