The mixture you liked at the Mahane Yehuda market, at Yossi's store: The best nuts are roasted with maple and coarse salt. Cashews, almonds , pecans, hazelnuts and sometimes more (depending on Yossi's mood that morning)
Not only a perfect snack, but also wonderful to smash on a green salad and rice pilaf.
Keep in a cool dry place for up to a month. It can be stored in the freezer for another six months.
