Dry roast the nuts together in a frying pan over medium-low heat for 2 - 3 minutes, until aromatic and until they take on a slightly golden colour.
60 g hazelnuts, 30 g pistachios
Do the same with the sesame seeds.
200 g sesame seeds
And finally, give the coriander and cumin seeds a turn in the hot frying pan for about a minute or two only. We want them only lightly roasted.
100 g coriander seeds, 30 g cumin seeds
Cool everything down for 10 minutes or so.
Place in a pestle and mortar and pound away to a coarse grind. The sesame seeds will probably defy you and stay whole, but that's ok!
½ tsp salt, freshly ground black pepper
Leave to cool completely and store in a clean jar as you would your other spices. Will last a good 6 months, although its potency will diminish with time.
