Grapefruit Jam

Directions

1. 1
   Peel the grapefruit, and remove all the white membranes, too.
2. 2
   Put the fruit pulp and sugar in a pan, mix lightly, and leave for about 5 minutes.
3. 3
   When some moisture comes out of the pump and the sugar starts to melt, add the lemon juice and start cooking over medium heat.
4. 4
   When it comes to a boil and some scum rises to the surface, skim it off 2 to 3 times.
5. 5
   (The white stuff in the middle of the photo is the scum.)
6. 6
   After simmering for 15 to 20 minutes, when the orange color darkens and the mixture thickens, it's done.
7. 7
   Even if it's quite liquid, it will thicken when it cools down.
8. 8
   Pour into a sterilized jar while it's still hot close the lid.
9. 9
   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.
10. 10
    Strain and add it to Step 3 and continue.
