Lemon Blossom

My train of thought has recently been fueled by some great photographic posts over at Eggbeater.   The pictures capture the birth of Spring (a bit early) with shots of almond and plum blossoms.  I began to think of the possibilities of using these flowers in cooking.  I was also reminded that in harvesting the flowers, you get no fruit.  A dilemma.  Well, as I pondered the scenario I looked up at our lemon tree and saw its one lone blossom.  Actually, it is not our lemon tree, we gave it to Marie as a gift several years ago.  We also bought trees at that time and managed to see them, well die.  Marie has kept hers alive and well, yielding several Meyer lemons each year.  Back to the subject at hand and the multitude of culinary possibilities.  What can we do with blossoms?  What should we do with blossoms?  And what if there is only one blossom?
