Pink Grapefruit Jelly Drink

Put the grapefruit juice into a pan with the sugar and bring to the boil.

Mix the agar powder in water, add to the pan and boil hard for 2 minutes.

Pour into a small container, e. g. a gratin dish and leave to cool.

Then put into the refrigerator for at least 1 hour.

Before serving cut the jelly into cubes and put into glasses.
