In a small saucepan cook the butter over moderate heat until it is golden brown, being careful not to let it burn, let it cool, and chill it just until it is no longer liquid. (The butter may be browned 1 day in advance and kept covered and chilled. Let the butter soften at room temperature before using.) In a bowl cream together the browned butter, the granulated sugar, and the brown sugar and beat in the egg, the vanilla, and the almond extract. Into the bowl sift the flour, the baking powder, and the salt and beast the dough until it is just combined. Chill the dough for 30 minutes and press it onto the bottom and side of a 9-inch tart pan with a removable fluted rim.
