This recipe is lacking one important ingredient: 'truth in advertising' LOL
Following the recipe to the letter, I obtained two-and-a-half 500g jars of a very nice-tasting spread - bit it wasn't goiabada, as it did NOT jell!
A few days later my wife used guavas from our tree to try her own version, and she succeeded at once...
But then, she uses 3/4 parts sugar to 1 part of cooked fruit! I1 cup sugar to 2 lb raw fruit gets you a nice, pureed spread...
