There are a lot of Dukkah spice variations. It can be made with Pistachios, Cashews or even Macadaemia nuts. So feel free to make it your own. It's a great spice to experiment with. This is the spice mix I use.
If you are using spice seeds, place them on a dry pan and toast them on low-medium heat until you start to smell them. If you are using ground spices, do the same thing, but be careful as they burn more easily. You just want the spices to release their aroma slightly.
Place the spices - toasted cumin, toasted coriander, chilli and salt (not sesame seeds) in the food processor and pulse until it you have chopped them fairly fine.
Add the almonds (chopped if you prefer) and process further until you have coarse almonds pieces and the the spices are fine.
