To make the Dukkah, you’ll need walnuts, almonds and a mix of spices and herbs. If you’re looking to play around a bit with the flavors, you can try bringing some other nuts like pistachios and hazelnuts into the play.  Green peppercorns, sunflower seeds, kosher salt, red pepper flakes, hulled pumpkin seeds and black sesame seeds are some other good additions you can consider throwing into the mix.
