Whether they're braving the Kingsroad during war, fighting beyond the Wall, or foraging in the last days before the long winter, acorn paste can satisfy travelers' hunger. Even children have no problem preparing this food in a moment of need. This spread goes nicely on biscuits and bread—a luxury in the wild. (A Clash of Kings, Chapter 19—Arya)
Though acorn paste may be unfamiliar to anyone who hasn't needed to forage, other nut butters are commonplace. As an alternative to store-bought peanut butter, make your own almond, walnut, or macadamia butter. To prepare, just heat nuts of your choice in the oven at 400°F for 6-8 minutes or toast them on the stovetop in a dry skillet. A quick run through a food processor with a little oil will finish up the spread.
