Preheat oven to 350°F (177ºC) and prepare parchment-lined 8½ x 4½-inch (1.5 litre) loaf pan.
In a large bowl, whisk together eggs, lemon juice and yogurt until smooth. Add sugar, lemon zest, oil and vanilla and continue whisking until well-integrated. Add flour, baking powder and salt and continuing to mix just until combined. Do not overmix. The batter will be thick, and you should still be able to see bits of flour throughout. This will result in a lighter, fluffier texture.
Using a spatula or wooden spoon, fold in 1 cup of the blueberries turning just until evenly distributed.
Pour batter into loaf pan and smooth it out into the corners. Arrange remaining berries across the top and gently press them into the batter. Finish with a sprinkle of turbinado sugar.
Bake for 65-75 minutes until golden and a tester comes out dry. Let bread cool in the loaf pan for exactly 10 minutes, then gently lift it out and place it directly onto a wire cooling rack to let air circulate completely around the bread. This loaf is delicious served at this point, still warm from the oven, with lots of butter. For a smoother cut, let cool completely before slicing.
