Directions

1. Combine flour, halvah, sugar, and salt in processor. Using on/off turns, process until blended to sandy texture.
2. Add butter. Using on/off turns, process until mixture resembles coarse meal.
3. Whisk egg yolks and 2 tablespoons ice water in small bowl to blend.
4. Add to flour mixture. Using on/off turns, process until moist clumps form. Gather dough into 2 balls; flatten into disks. Wrap separately in plastic. Chill 1 hour.
5. Combine sugar and 1/2 cup water in heavy large saucepan. Stir over medium heat until sugar dissolves. Increase heat to high and boil until syrup turns deep amber or clip-on candy thermometer registers 360°F, occasionally swirling pan and brushing down sides with wet pastry brush, about 11 minutes (time will vary depending on size of pan).
6. Remove from heat. Carefully stir in cream (mixture will bubble).
7. Add butter and whisk until melted and smooth. Stir in pistachios. Cool until lukewarm but still pourable, about 30 minutes.
8. Meanwhile, preheat oven to 350°F. Lightly spray 9-inch-diameter tart pan with removable bottom with nonstick spray.

15. Remove top paper from second dough disk. Invert over filling.
16. Remove paper. Press dough around pan edges to trim and seal.
