For Shrimp: Bring water, lemon, and bay leaves to a boil, covered, in a medium pot. Add 4 tablespoons of salt. Reduce to low heat and allow salt to dissolve for 8 minutes.
Return water to a boil and add shrimp. Cook until bright pink—about 2 minutes.
Immediately drain, and place shrimp in an ice bath.
To serve shrimp, fill a bowl with ice, and layer on top.
Platter: Placing your shrimp in the center, place remaining vegetables and spreads around it. Garnish with basil or other greens and enjoy cold!
