Then roast the sesame seeds till they become a pale brown.
Roast the coriander seeds, cumin seeds, fennel seeds, peppercorns till they become fragrant.
Put everything in a grinder and grind till you want the desired level of blend, slightly coarse or fine.
Store dukkah in an air-tight container in the refrigerator.
Notes
To increase the hotness you can add some dry red chilies or even red chili flakes.
Adding dry mint will give a fragrant coolness to the duqqa.
Some dukkah recipes have also marjoram, zatar and chickpeas added in it.
Cool all the ingredients after they have been roasted. If you put them hot or warm in the grinder, then due to moisture they clog to each other and become paste like.
Explore with the seeds, nuts and spices & create the fusions and flavors you like.
