Blueberry Orange muffins

Makes 5
I simply love baking and I find that Orange adds a very unique flavor to anything baked with it.These muffins are not very sweet, but taste very good and make great breakfast muffins.This recipe is from 'Baking from my home to yours'. I don't own the book, and this recipe really makes me wish I had the book :)
