Preheat oven to 375 degrees. Butter 12 cup bundt pan.
Prepare cake:
With an electric mixer beat the cake mix with the water, oil and eggs, adding the orange zest to batter. Pour into prepared pan and bake 35-45 minutes or until tooth pick inserted in center comes out clean.
Meanwhile, make syrup:
Heat orange juice, sugar and Tabasco sauce in a medium saucepan. Bring to a boil and reduce heat; simmer uncovered for 5 minutes. Remove from heat, and reserve 1/4 cup of this syrup for glaze.
Remove cake from oven. With a wooden skewer, poke holes in cake in several places, without removing it from pan. Spoon the syrup evenly over cake. Cool cake in pan 10 minutes.
Carefully invert cake onto a wire rack to cool completely.
Combine reserved syrup and confectioner's sugar in a small bowl until smooth. Place cake on a platter and spoon glaze over cake to decorate. Garnish with orange peel curls, if desired.
