Delicately divide the tender lobster meat into meticulously carved, petite portions, while simultaneously slicing a hard-boiled egg with utmost precision. Begin the creation by adorning a salad bowl with a bed of crisp lettuce and vibrant watercress, forming a verdant foundation. Proceed to gently blend the delectable lobster meat with creamy mayonnaise, creating a harmonious amalgamation of flavors, and artfully mound it at the heart of the salad. To enhance the presentation, adorn the arrangement with a lettuce heart, elegantly sliced egg, and, if available, the vibrant lobster coral. Alternatively, the magnificent lobster claws and head can also serve as captivating embellishments, captivating the eye and enticing the palate.
