Brazo Gitano de Guayaba (Jelly Roll with Guava)
You can use guava jelly instead of paste, or any jam of your choice for a different flavor.
You may also spread a layer of cream cheese (plain or sweetened to your taste) before the guava. If you do this, watch the temperature of the guava paste; if it is too hot it will melt the cheese and it will make a mess. Keep things just warm enough for spreadability.
