I love grapefruit but I have also been annoyed by how much I have felt was wasted in the way that I have always ate them. In my family growing up we always just cut them in half and scooped out what we could with a spoon. I think my grandma even had special little spoons that the had jagged edges.
So I set out to find a way to not waste any edible part of a grapefruit. Maybe everyone else already knew how to do this --- but I want to share anyway.
Put a pan of water on to boil. When the water is boiling remove the pan from the heat source and put your unpeeled grapefruit in the water. Let it sit for about 5 minutes. Carefully remove the fruit from the water and as soon as you can touch it begin to peel. You will be able to easily removed the thick white stuff... I don't know what it is called. Once you have that removed you will be able to easily break apart each section and remove all of the section casings.
I cannot believe how easy this was! Oh yeah and the inside of the fruit really doesn't get hot when you do this.
