Haven't made this yet, but noticed that there is some discussion in the reviews about what one is meant to do with the orange. Bluemoon72 is wrong on this one-- what is intended is called making "supremes" as an earlier reviewer mentioned. This is done by cutting off the two ends of the citrus, then cutting off the pith and peel in strips with a paring knife (when I first learned to do this it reminded me of skinning a pineapple). This will leave you with the fruit in segments and the membranes between each segment. With the paring knife cut along each membrane to separate the individual segments. This gives you pretty, intact segments for your salad without any pith or membrane. Talking about lemons was a confusing move by the author, I've only once done this with lemons but supreme oranges and grapefruit all the time.
