Ran across a recipe for orange-basil biscotti, but since we prefer the more cookie-like mandelbrot, I adapted this recipe to great results.
Substitute 1 T. Basil, freshly chopped and the zest of one orange for the chocolate chips. And, I also substituted roasted and chopped hazelnuts for the walnuts. Spectacular!
After over-night refrigeration, I shaped the batter into two logs, approximately 3" dia. x 10" long.
Just out of the oven...
Cool for 10 - 15 minutes, slice slightly on the diagonal. Brush cut side with melted butter; sprinkle with cinnamon-sugar. Return to 300 degree oven for 30 minutes (or more) to finish drying. Store in airtight container.
