Preheat oven to 150 degrees fan forced
Line a large baking tray with baking paper, and place rack into middle of oven
In a medium sized mixing bowl, whisk the egg white until foamy
Stir in the sugar and spices and mix well
Add the nuts and stir well to thoroughly incorporate
Tip the nut mix onto the lined tray and spread out into a single layer
Bake for 15 minutes, remove tray and stir mix around, then spread out again into a single layer again (they will be a little tacky but will dry out during the next bake)
Return tray to oven and continue to bake for a further 15 minutes, or until nicely golden brown (it takes a total of 30 minutes in my oven)
Allow nuts to cool on tray, where they will harden up and become crunchy
Store in an airtight container in the pantry for up to three weeks
