Egg whites. Nature’s food glue. What sort of nuts to use? Any nuts you like. We used almonds, pecans and cashews for this batch. As for the spices, we used chipotle powder for its smokey spiciness. You could easily use regular chili powder, cayenne, Chinese Five Spice, or Garam Masala. Just remember you’ll want something sweet, something spicy, salt, something zesty, and a touch of acidity. Add the brown sugar and chipotle powder and mix well. Whisk in the egg whites. Remove from oven, sprinkle lime juice over all the nuts and return to the oven for 2 minutes. Allow to cool before eating. Pretzel and Nut Mix - holiday snack from David Lebovitz
