Like most Italian foods, so simple, and so good.
INGREDIENTS
2 1/2 cups walnut halves or large pieces
3/4 cup brown sugar
1/2 teaspoon cinnamon
1/4 tsp. ground ginger
1 large egg
Preheat the oven to 375°F. Line a baking sheet with baking mat.
Combine the walnuts, sugar, and cinnamon in a food processor and process to make a fine meal the texture of sand. Transfer to a bowl. Make a well in the middle and add the egg. Use a fork to briefly whisk the egg, then begin incorporating the nuts until everything is thoroughly combined, finishing the mixing with your hands. The dough will be quite moist and a little sticky.
Divide the dough into quarters. On a flat surface, shape one piece of the dough into a 6-inch log about 1 inch high, flattening the sides to make a bar about 1 inch on each side. Cut the bar into 3/4-inch segments to make eight pieces.
Space the cookies evenly on the prepared baking sheet, standing upright (not on a cut side) with 1 inch of space all around for spreading. Repeat with the remaining bars to make thirty-two cookies.
Bake the cookies on the upper oven rack for about 15 minutes, until they are golden all over. Let cool on the pan.
