Candied Grapefruit Peel.
Cut the ends off the grapefruit.
Lay the fruit on one cut side, then with a sharp knife, remove the peel in sections, working around the fruit.
Cut from top to bottom, taking both the peel and the pith. (You may even get a little piece of flesh - which is allowed.)
Cut the peel into long strips (size of course depending on your grapefruit). The strips will swell so make the strips around 1cm (1/4 inch) wide, no more.
Place strips into a large pan, allowing no more than two layers deep.
