To make the dough cut 1/2 cup butter into 1 cup flour using a knife or pastry blender. Add water as needed and mix until crumbly, leaving pea sized chunks. On a floured surface roll the dough out to 3 or 4 inches in width. Place on a rectangular cookie sheet.
In a small saucepan over high heat, bring 1 cup water and 1/2 cup butter to a boil. Remove from heat and stir in flour; mix until smooth. Beat in eggs one at a time, mixing well after each. Stir in 1 teaspoon almond extract. Spread over dough.
Bake in preheated oven for 55 to 60 minutes. The pastry will fall a little as it cools.
Meanwhile, combine confectioners' sugar, cream, 1 tablespoon butter and 1 teaspoon almond extract. Spread over pastry as soon as it's removed from the oven.
