It took three batches to get these Blood Orange Spice Muffins right. It was a true exploration into the world of muffindom. What makes them tender? What makes them sweet? How can you bring out flavor and play with texture to create something wonderful, and still keep it healthy? Big questions, indeed, and with a good solid year and a half of muffin-making behind me, I decided it was time to be bold and venture where no muffin in my kitchen had gone before: an original recipe from scratch.
