Tastes wonderful on toast! My mother's recipe and its foolproof. The beauty of it is that there are no fixed measurements. I make my jelly sometimes with just four guavas. Other times, it may be for 5 lbs...the measurements of all the ingredients increase or decrease depending on the liquid extracted.
10For every cup of liquid add one cup of sugar and one tablespoon of lemon juice.
11(Eg. if there are four cups of liquid you would need to add four cups of sugar and four tablespoons of lime/lemon juice.) Put this mixture back on fire and bring to a boil.
12Lower heat and cook, stirring constantly (as the liquid tends to boil over), till the liquid starts coating the spoon thickly and the juice/jelly drips from the spoon in jointed drops.
13Let stand for half an hour and pour into jars while still warm.
