"Gypy's Arm" (Jelly Roll with Guava Cream Filling) Brazo de Gitano)

Eons ago in college, Cuban friends introduced me to the joys of guava and queso blanco--in New York it was cream cheese combined with guava paste on crackers (gallegos) sold in every bodega on the Upper West Side. Combined with cafe con leche, it was breakfast from heaven. This cake is a simple genoise, filled with that magical combination rolled up into a pretty "Gypsy's Arm." I go with the guava pasta which comes in tins rather than a guava jelly.
