Rhubarb Custard Tart

For this Rhubarb Custard Tart, I followed Cresent Dragonwagon's Passionate Vegetarian recipe.  The crust is particularly worth mentioning, even though it isn't in the photo.  Rather than being a traditional tart crust, this one is a more rustic, hearty crust.  It is multigrain and has wonderful toasted sesame seeds that burst with flavor.
