COOKING TIPS:
1. Quality shrimp should not have a black dot on its head because this is a major sign that the shrimp is not fresh and its head is likely to come off.
2. "Devein" means removing the ugly dark "vein" along the shrimp's back, which is actually the shrimp's digestive tract with a lot of sand and makes the shrimp taste gritty and bad to the palate.
