Preheat the oven to 350ºF/180ºC.
Place nuts on a baking tray and roast for a few minutes - keep your eyes on them because they could burn in an instant.
Remove from oven and transfer to a clean tea towel. Rub gently to remove skins from hazelnuts.
Dry fry sesame seeds and spices in a frying pan until fragrant.
Mix in the nuts and transfer to a food processor. The mix needs to have a slightly coarse texture, so do not over process. Use immediately or store in an airtight container, it will keep for up to 2 months.
