I have never gone wrong with asparagus...
ASPARAGUS CUSTARD TART
For pastry
1 cup all-purpose flour
1/2 teaspoon salt
3/4 stick (6 tablespoons) cold unsalted butter, cut into 1/2-inch
cubes
1 large egg, lightly beaten
For filling
1 medium leek (white and pale green parts only), quartered
lengthwise, then cut crosswise into 1/3-inch pieces
1 lb medium asparagus, trimmed
1 tablespoon unsalted butter
1/2 teaspoon salt
1/2 teaspoon black pepper
1 1/3 cups heavy cream
3 large eggs
2 teaspoons finely chopped fresh tarragon
2 teaspoons water
Special equipment: parchment paper; a 9 1/4-inch flan ring* (see
cooks' note, below)
Make pastry:
Blend together flour, salt, and butter in a bowl with your
fingertips or a pastry blender (or pulse in a food processor) until
most of mixture resembles coarse meal with some small (roughly
pea-size) butter lumps. Drizzle evenly with egg and gently stir with
a fork (or pulse in processor) just until a dough forms.
Turn out dough 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 to help distribute fat. Gather dough into a
ball, then flatten into a 5-inch disk. Chill dough, wrapped in
plastic wrap, until firm, at least 30 minutes.
Make filling while pastry chills:
Wash leek in a bowl of cold water, agitating water, then lift out
leek and pat dry.
Cook asparagus in a wide 4- to 5-quart pot of boiling salted water,
uncovered, until just tender, about 5 minutes. Transfer asparagus
with tongs to a bowl of ice and cold water to stop cooking, then
drain and pat dry. Cut off and reserve tips (leave more stalk if
asparagus is thin), then thinly slice stalks crosswise.
Heat butter in a 10- to 12-inch heavy skillet over moderately low
heat until foam subsides, then cook leek with 1/4 teaspoon salt,
stirring, until softened, 6 to 8 minutes. Stir in sliced asparagus
and 1/4 teaspoon pepper and remove from heat.
Finish filling and assemble and bake tart:
Put oven rack in middle position and preheat oven to 375°F.
Line a baking sheet with parchment paper and put flan ring in center
of baking sheet. Roll out dough on a lightly floured surface with a
floured rolling pin into an 11-inch round, then fit dough inside
flan ring, pressing dough against bottom edge and side of ring. Run
rolling pin over top edge of ring to cut off excess dough.
Whisk together cream, 2 eggs, tarragon, and remaining 1/4 teaspoon
salt and 1/4 teaspoon pepper. Lightly beat remaining egg with water
in a small bowl and brush tart shell all over with some egg wash.
Spoon asparagus mixture into shell, spreading evenly, then pour
cream mixture over asparagus.
Bake tart until filling is just beginning to set but still loose on
top, 20 to 25 minutes. Scatter asparagus tips over top, pressing
lightly if necessary to help them settle into filling, then continue
to bake until custard is golden and just set but still slightly
wobbly in center, about 30 minutes more (custard will continue to
set as it cools).
Cool tart on baking sheet on a rack until warm, about 30 minutes.
Loosen edge with a small sharp knife, then lift off flan ring. Serve
warm or at room temperature, cut into wedges.
Cooks' notes:
• Pastry dough can be chilled up to 1 day. Let stand at room
temperature until slightly softened before rolling out.
• If you don't have a flan ring, you can use a 9- to 9 1/4-inch tart
pan with a removable bottom instead. Put a baking sheet in oven
while preheating, then bake tart on sheet.
• Tart can be baked 2 hours ahead and cooled completely, then kept,
loosely covered with plastic wrap, at room temperature. If desired,
reheat in a preheated 350°F oven until warm, 15 to 20 minutes.
