Why is my lobster tail black?
Simply so, why does lobster turn black?
Answer: When many lobsters turn black during/after cooking, I tend to think that they were improperly cooked. When the internal temperature during cooking doesn't reach a certain level, the enzyme 'phenoloxidase' can get activated, resulting in the deposition of melanin, or black pigment.
Herein, what is the black stuff inside lobster tail?
"Actually the black gelatinous fluid is the 'roe' or 'coral,'" said Berry. "The tomalley, or liver/pancreas, is the green substance. If you are lucky enough to get some of the coral, remove it from the lobster and cook it separately in a little butter until it is bright red.
These are immature eggs called roe and are naturally black. If the eggs are black and not red when you are ready to eat your lobster, that means the lobster needs to be cooked further. Once the eggs are red — meaning they're cooked — they can be eaten.
