Spanish Shrimps in Garlic Sauce

We had a lot of fun doing a cooking class in a trained chef's house while we were in Madrid.
The easiest thing that we made was this traditional tapas dish.  One thing that we did with the shrimp shells was to make them into a stock for a paella, which is something that we could do but almost never do.
This is a quick and easy dish that is so delicious.
