So, i'm wanting to attempt sugared fruit for these cupcakes I am doing for a challenge. I want to do sugared fruit...but I want to do cut up slices of limes 
is this going to work? how long will they last with the egg whites and sugar on there? how far in advance can I do these?? I'm sure I can accomplish them but i just don't want to make them too far in advanced and i'm wondering if the exposed fruit will soak up the sugar and it won't have that effect i want
HALP 
I was going to try to answer you until you said they were going to be sliced...I think the acide and moisture would effect the sugaring but that said all you can do is try it. I did sugared cranberries and rosemary for a christmas cake but I only did it a day in advance. I wish I could give you more help.
Good luck.
Slice them and leave them on the counter to air dry overnight. They'll get a skin on them from being dry. Not sure it'll work but that's where I would start for a trial run. Freshly sliced will def. not work.
I've candied lemon slices in the past, the process is not complex but takes timmmmmme!
But... check this: http://www.bellaviva.com/new/driedfruitsnuts/apples-oranges/lemons-10901.htm
with these slices as start point you can make candied lemons in no time; just soak dried slices in a solution of two parts honey to one part water. Let dry either on air or in a very low oven. Repeat two times. Once half way dry, dip in white crystal or sanding sugar for a better look, let dry completely and keep on air tight container.
hope it helps
