This explanation is from a Spanish portal site I saw recently
"Hay Churros"you can find a recipe here
If you spot a sign in Spain saying 'Hay Churros' at breakfast time go in and ask for 'Chocolate y Churros por favor'. What will arrive is the thickest cup of hot chocolate you have ever seen with a plate of deep fried 'fritters'. You eat this by dipping the churros in the chocolate (this is perhaps not for weight watchers).
So when we went to Barcelona last week I was eager to show my friend Terri this dream in a cup. After visiting the Sagrada Familia, the cathedral built by Gaudi, we meandered up the lovely old streets. We found a pastry shop with streetside tables and ordered a cup to share. Terri immediately dubbed the cup full of hot pudding like chocolate "Chocolate Porn" which is a pretty apt name... It really does spoil you for regular old hot cocoa.... The Cup we had was from a menu of different types. I chose the merangue one which had little dollops of crystalized eggwhites and sugar sprinkled on top. I definately do not want to wait years again to have this treat. So I will be trying the recipe at home, now that I have found one!
Here's to Chocolate Porn!
