Grapefruit Jam - sugar

Method

• Peel the grapefruit, and remove all the white membranes, too.
• Put the fruit pulp and sugar in a pan, mix lightly, and leave for about 5 minutes.
• When some moisture comes out of the pump and the sugar starts to melt, add the lemon juice and start cooking over medium heat.
• When it comes to a boil and some scum rises to the surface, skim it off 2 to 3 times.
• (The white stuff in the middle of the photo is the scum.)
• After simmering for 15 to 20 minutes, when the orange color darkens and the mixture thickens, it's done.
• Even if it's quite liquid, it will thicken when it cools down.
• Pour into a sterilized jar while it's still hot close the lid.
• If you prefer to have a bitter taste: finely shred about 1/2 of the peel, and simmer for about 5 minutes to get rid of some of the bitterness.
• Strain and add it to Step 3 and continue.
