[Sca-cooks] Date for Spanish Garlic Soup?

[Kean Gryffyth]

Greetings all,
    My Lady and I recently had dinner a small family run Spanish 
restaurant, where we had a simple garlic soup that seemed as if it might 
be a period recipe. It was a broth, probably beef, with crushed garlic, 
egg (seemed to be almost like egg drop soup in the way the egg was done) 
with dried bread chunks floated on top. Does anyone know of a period 
recipe for a soup like this? The soup was served hot, btw.
