Does anybody know how many carbs are in an orange, including the skin? The recipe I use for orange and almond muffins calls for a whole pureed orange and I can only find the carb count for a peeled orange.

According to "The Nutribase Nutrition Facts Desk Reference"--

All Commercial Varieties (approx. 2 5/8" diameter):
62 cal., 15.4 carbs, 3.1 fiber, .

California Navel Orange (approx 2 7/8" diameter):
64 cal., 16.3 carbs, > 0.6c fiber

California Valencia (approx 2 5/8" diameter):
59 cal., 14.4 carbs, > 0.6c fiber

Florida (approx 2 5/8" diameter):
69 cal., 17.4 carbs, 3.6c fiber

Take your pick...they're all pretty close.
