4 crepes, for example from this recipe with the addition of 2 tablespoons sugar
Preparation
Cut the vanilla bean lengthwise and scrape out the seeds with a teaspoon.
Bring the cream to a boil along with the vanilla bean, scraped seeds and half the amount of sugar. Remove from heat as soon as it starts to boil. Let it rest for 1 hour to absorb the vanilla flavor (I didn't wait the prescribed hour, but heated the cream for 8 minutes to thicken it slightly. The chilled cream will be thicker than the heated one).
Peel the pears and cut into pieces. Fry in a pan or small pot with butter and the remaining brown sugar.
Arrange the hot pears on the hot crepes, fold the sides of the crepe and pour with vanilla cream.
