For the pastry dough:
1¼ cups all-purpose flour
¾ stick (6 tablespoons) cold unsalted butter, cut into 1/2-inch cubes
2 tablespoons cold vegetable shortening
¼teaspoon salt
2 to 4 tablespoons ice water

Blend together flour, butter, shortening, and salt in a bowl with your fingertips or a pastry blender (or pulse in a food processor) just until most of mixture resembles coarse meal with small (roughly pea-size) butter and shortening lumps. Drizzle evenly with 3 tablespoons ice water and gently stir with a fork (or pulse in processor) until incorporated.

Squeeze a small handful: If it doesn’t hold together, add more ice water, 1/2 tablespoon at a time, stirring (or pulsing) until just incorporated, then test again. (If you overwork mixture, pastry will be tough.)

Turn out mixture onto a lightly floured surface and divide into 4 portions. With heel of your hand, smear each portion once or twice in a forward motion. Gather dough together with scraper and press into a ball, then flatten into a 5-inch disk. Chill dough, wrapped in plastic wrap, until firm, at least 1 hour.

For the tart:
1 recipe Pastry Dough (see above)
1 cup heavy cream
1 whole large egg
2 large egg yolks
¼ teaspoon salt
¼ teaspoon black pepper
5 oz chilled Stilton, rind removed and cheese crumbled (1½ cups)

Make tart shell:
Preheat oven to 350°F.

Roll out dough on a lightly floured surface with a floured rolling pin into a 17- by 8-inch rectangle and fit into tart pan. Trim excess dough, leaving a 1/2-inch overhang, then fold overhang inward and press against side of pan to reinforce edge. Lightly prick bottom and sides all over with a fork. Chill until firm, about 30 minutes.

Line pastry shell with foil and fill with pie weights. Bake in middle of oven 20 minutes, then carefully remove foil and weights and bake until golden, 10 to 15 minutes more. Cool shell in pan 20 minutes.

Reduce oven temperature to 325°F.

Make filling:
Whisk together cream, whole egg, yolks, salt, and pepper until combined.

Put tart shell (still in pan) on a baking sheet and scatter cheese evenly in shell. Slowly pour custard into shell and bake in middle of oven until golden around edge and custard is just set, 30 to 35 minutes. Cool tart completely in pan on a rack.

Cut tart into 32 rectangles and serve at room temperature, topped with chutney.

(Dana’s Make Ahead Tips:  You can make the pastry dough up to one month in advance, wrap it well, and freeze it.  Allow it thaw overnight in the refrigerator before using.  You can blind bake the shell earlier in the day and let it cool completely before filling and continuing to bake.  Finally, you can wrap the whole tart well, still in its pan, and refrigerate it overnight.  Allow it to come to room temperature for several hours before serving or heat it for about 10 minutes in a low oven.)
