Preheat oven to 100C/375F. Place crab meat in bottom of pastry shell.
Cut bottom parts of asparagus spears into half-inch slices and scatter
over crab. Scatter parmesan over asparagus. Beat eggs and milk together,
and season to taste with nutmeg, cayenne and salt. Pour over
crab/asparagus mixture. Arrange reserved asparagus tips in a spoke-like
pattern on top. Bake in preheated oven until set (about 45 minutes to an
hour).
