I bought 5 scallops with the coral attached today for 5 quid?

They were frozen -so am defrosting now- how is the best way to cook? I have bought M+S before but they were just the small affairs! these are big guys-I am thinking a little er and oil and pan fry for a couple of minutes? all suggestions gratefully received- I love scallops but would love a very austere recipe ,just to bring out the sublime flavours of this most delicious food.
