* If you're completely oil free, you could try substituting apple sauce for the oil. The muffins will have a gummier texture, but will certainly be better for you!
** If blood oranges are not in season, regular oranges will work in this recipe.
*** To make a quick glaze, simply add 1 T. orange juice to ½ cup powdered sugar and stir vigorously. Add more OJ for a thinner consistency, if desired.
Keep muffins in an air-tight container up to four days (if they last that long!).
I recommend reheating the muffins in the microwave about 10 seconds before serving, if not serving them right after baking.
