Berries, and especially blackberries, are a common theme for Lughnassadh. Here in the south, blackberries grow everywhere in the wild, and I can remember gorging on them all summer as a child (and now as an adult, too!) For a great treat, try this delicious cookie recipe from Southern Living.
Preheat oven to 350°. Bake almonds in a single layer in a shallow pan 6 minutes or until toasted and fragrant, stirring halfway through. Cool completely (about 20 minutes). Reduce oven temperature to 325°.
Process almonds in a food processor 30 seconds or until finely ground.
Beat butter at medium speed with a heavy-duty electric stand mixer until creamy. Gradually add 1 cup powdered sugar, beating well.
Combine flour, next 3 ingredients, and almonds; gradually add to butter mixture, beating until blended.
Shape dough into 3/4-inch balls, and place 2 inches apart on parchment paper-lined baking sheets. Press thumb into each ball, forming an indentation.
Bake at 325° for 12 to 15 minutes or until edges are lightly browned. Cool on baking sheets 2 minutes. Transfer to wire racks, and cool 30 minutes.
Place preserves in a zip-top plastic freezer bag; snip 1 corner of bag to make a small hole. Pipe preserves into indentations.
