Middle Eastern friends introduced me to Palestinian-style dukkah, which is based on wheat berries rather than on the nuts used in Egyptian-style dukkah. While some of the recipes I've tried at home get close, none achieves the long, savory finish of the first dukkah I tasted. In fact, the label for that product clearly does not identify all of the ingredients, as I can taste a tangy flavor that is not represented by any of the listed ingredients.
Wondering if a particular sea salt might be the champion and, after reading other salt-spice-umami posts on this forum, I see that there are "sea salt" products on the market which add porcini, black garlic, kelp or "vegetable extract."
I'm hoping a reader familiar with Palestinian cuisine can get me over the flavor finish line.
