Measure the pistachios and pumpkin seeds into a dry nonstick pan or cast iron skillet.
Toast over medium heat - stirring constantly - until just beginning to get fragrant. Add the sunflower seeds and coriander seeds, toast for another minute or so, until THEY start to smell roasty.
Add the sesame and cumin seeds, continue toasting for another minute or so.
Transfer toasted nut and seed mixture to a mini food processor, blitz until it’s as fine as you’d like it. I like to keep it on the chunky side - I can always process it down finer if a specific use needs that!
While still hot, stir in the salt.
Allow to cool - uncovered - to room temperature, then store in an airtight container.
Notes
Best when used within a day or two, but it’ll keep for a few weeks.
