Preheat oven to 375°F. Lightly oil a 9 × 5-inch loaf pan.
In a large bowl, sift together unbleached flour, evaporated cane sugar, baking powder, and baking soda.
In a separate bowl, whisk together vegan yogurt, orange juice, and grapeseed oil.
Pour wet ingredients into the flour mixture and stir quickly, with a light hand, until just combined.
Spoon the batter into the prepared loaf pan, and only then, sprinkle the blueberries on top, so the whole bread is studded with them.
Bake for 1 hour or until the bread puffs and turns golden and springs back to the touch.
Slices best when cool. Irresistible when warm. Freezes beautifully.
If you absolutely must make muffins, prepare above, then spoon batter into a prepared muffin tin, filling cups 2/3 full. Bake for 20 minutes or until tops are puffed, pillowy, and golden-brown.
Makes one loaf, serves 8 to 10.
