Quick Grapefruit Marmalade

Directions

1. 1
   Slice the grapefruit very very thinly with a sharp knife, into flat slices. then cut these into strips, and cut the strips into smaller bits. Keep all the juice that flows out, if it's a juicy grapefruit.
2. 2
   Bring 6 cups of water to a boil, and then add the grapefruit slices and juice.
3. 3
   Keep at a low boil, adding the sugar. Continue boiling for quite some time (20-30 minutes), until it begins getting thicker.
4. 4
   The tricky part is knowing when to stop boiling. If you wait too long, it will become too thick when it cools. The important thing to know is it thickens a bit when cooling, so you have to stop it before it reaches the desired consistency. I put a porcelain dish in the fridge, then pour a little onto the dish - if it congeals a little, then it's ready.
5. 5
   Before you bottle it, eat it with bread while it's still warm - it's delicious!
6. 6
   Pour in any clean bottle, and refrigerate.
