Pine Nut Caramel Shortbread Recipe

In a large bowl, cream butter and sugar until light and fluffy. Combine flour and salt; gradually add to creamed mixture and mix well. Pat onto the bottom of a greased 15x10x1-in. baking pan. Prick dough thoroughly with a fork. Bake at 375 ° for 15-18 minutes or until golden brown. Cool on a wire rack. Reduce temperature to 325 °. In a large saucepan, combine the butter, brown sugar, honey, sugar, cream and salt. Cook, stirring occasionally, until a candy thermometer reads 234 ° (soft-ball stage). Remove from the heat; stir in pine nuts and vanilla. Spread evenly over crust. Bake for 20-25 minutes or until bubbly. Place pan on a wire rack. Sprinkle the top with coarse salt if desired. Cool completely. Cut into bars. Store in an airtight container.
