NOTE: Cooking time is refrigeration time. Serving size is a guess. This recipe was one of several passionfruit recipes in an expat magazine. I haven't tried them yet, but these little gelatin squares sound really good! Passionfruit is yellow here, and is sweeter than the purple variety found in the US. This may require that you add a bit more sugar, although a can of sweetened condensed mik sounds pretty sugary to me. Adjust sugar to your taste before adding the egg whites.
