Preheat oven to 350ºF and oil an 8-1/2 x 4-1/2-inch loaf pan (See Kitchen Notes).
Pour the maple syrup into a medium bowl, then add the Greek yogurt and sugar and whisk together until smoothly blended. Add the 3 eggs, one at a time, mixing well, then add the vanilla and stir again.
Sift the flour and then measure it into another bowl. Add the baking powder, coriander, 2/3 of the lemon zest, the ginger and salt, and stir lightly.
Gradually add the maple syrup into the dry ingredients and stir until smooth. Finally, pour in the olive oil and mix well. The batter will be beautifully shiny.
Pour into the loaf pan and place in the center of the oven. Bake about 50 minutes or until a thin blade inserted near the center comes out clean. By the way, the outside of the loaf will be a beautiful, unusual orange color. I did not expect that at all—the batter is a fairly conventional beige.
Place the pan on a rack to cool and run a thin blade around the inside between the loaf and the wall of the pan. When the loaf has cooled (and you can do this when it is still slightly warm), tip it out of the pan.
