I'm not really into gift-giving (or Christmas) so I usually bake cookies or cupcakes for the in-laws instead of buying gifts. This year I went with a candied orange peels recipe from the whole foods website. The recipe doesn't mention how long they take to make but it took me about 7 hours and that's before the 3-5 hours of drying on cooling racks (mine only dried for 30 minutes because Martha Stewart said it was ok). I used 3 oranges, 4 lemons, 4 limes, and 2 grapefruits.
Peeling the fruit and removing the pith took about 3 hours.
But it's so worth it.
