Melt butter slowly over low heat in a large or medium skillet.
Once the butter is melted, start adding the shrimp to the pan. Slowly cook the shrimp over low heat for about 5-7 minutes then flip and cook for another 3 minutes.
The shrimp are done when the internal temperature reaches 125°F or when the translucent flesh becomes opaque at the thickest part of the shrimp.
