Preheat your oven to 200°C/400°F and line a muffin pan with muffin cups and set aside.
In a large bowl, whisk together the flour, baking powder, baking soda and salt.
In a medium bowl, whisk together the oil, water, yogurt, sugars, vinegar, fresh and powdered ginger and cinnamon.
Core and dice the pear into pea-sized cubes and set aside. Peeling is optional.
Add the wet ingredients to the dry and stir until mostly incorporated. Then fold in the diced pear until a homogeneous batter forms.
Portion it out evenly into the muffin cups, they’ll be almost full. Top with coarse sugar.
Bake for about 25 minutes or until a toothpick inserted in the center comes out clean. If the top browns too quickly, cover loosely with aluminium foil and continue baking.
Let them cool for a minute or 2 in the pan before transferring them to a wire rack to cool completely.
