How Do You Know When Lobster Tail Is Done Boiling?
When the lobster tail is done boiling, the meat inside will be opaque and white, and the shell will be bright red. The internal temperature of the meat should reach 140°F (60°C). Another way to test is to insert a meat thermometer into the thickest part of the tail without touching the shell; if it reads 140°F (60°C), the tail is ready to be removed from the water.
