1. 1

   Whisk first 4 ingredients in small bowl to blend. Whisk egg yolk and 1 tablespoon whipping cream in another small bowl to blend. Using electric mixer, beat butter and sugar in medium bowl until blended. Beat in yolk mixture (mixture may look curdled). Beat in flour mixture just until blended (dough will be slightly sticky). Using floured hands, gather dough together and form into disk. Wrap in plastic; chill at least 1 hour. DO AHEAD:

   Keep chilled. Let soften slightly at room temperature before rolling out.

   Position rack in center of oven and preheat to 375u00b0F. Roll out dough on lightly floured parchment paper to 9-inch round. Using 8 1/2-inch-diameter plate as guide, cut out round. Transfer dough round, still on parchment, to baking sheet. Pierce dough all over with fork. Bake until crust is golden brown and baked through, 28 to 30 minutes. Cool crust completely on baking sheet. DO AHEAD:

   Combine 1 cup sugar, 1/3 cup water, and corn syrup in heavy medium saucepan. Stir over medium-low heat until sugar dissolves. Increase heat and boil without stirring until mixture turns deep amber, occasionally swirling pan and brushing down sides with wet pastry brush, about 10 minutes. Immediately pour caramel into 9-inch-diameter cake pan with 2-inch-high sides. Using oven mitts to protect hands, tilt pan to swirl caramel over bottom and halfway up sides of pan. Cool while preparing custard.

Gradually whisk hot rum mixture into yolk mixture. Pour mixture through fine strainer into cake pan with caramel. Place cake pan in large roasting pan. Add enough hot water to roasting pan to come halfway up sides of cake pan. Cover roasting pan loosely with foil.
