Is starting with the spanish cuisine by spanish shrimp salad recipe a good idea, can it be made the authentic way here in america, how?

I have been thinking of trying my taste buds with the spanish drink recipes from quite some time and to tell you frankly I have grown quite fond of the spanish ways and can’t wait anymore. Is starting with the spanish cuisine by spanish shrimp salad recipe a good idea, can it be made the authentic way here in america, how? I have checked the net completely and have found out about the modern versions minus the ones I am seeking, will you help me with the authentic ones?
