We start by cutting the lemon in half, from top to bottom, and gutting out everything inside. The helf-lemon shells will be used as molds for the jello.
Later, you mix any type of jello.. We prefer Lime flavor, it would go nicely with the smell of the natural lemon.
Then, use a spoon to pour the liqued jello in the lemon molds
Keep them in the firdge for a few hours to cool down and harden; I prefer to leave them overnight. Then, you cut them in halfs (again, top to bottom), resulting in nice presentable shapes.
