Makes one 10 x 14-inch tart
* Don't throw away those leftover dough scraps! Roll thin, place on baking sheet, sprinkle with cinnamon and sugar. Bake until browned.
** My biggest problem with the tart: my border was too big. I measured just over an inch but there was also a little spread with baking. I'd recommend ¾ inch instead, or smaller if you think you can keep your jam from oozing out. My large border impeded blood orange placement to its fullest potential in this blood orange tart, you know, the whole point of this recipe.
*** If short on time and planning this for breakfast instead of dessert, assemble everything the night before except the citrus rounds and butter dots on top. Chill the tart overnight (jam and almond cream spread on top like the photo above) wrapped well. Add the citrus and butter in the morning and bake. Anyone in the house not already awake will be easily lured to the kitchen.
