In a large bowl, mix the curd and sugar until the sugar slightly dissolves. Add the baking powder and baking soda and let it rest for about 2 minutes as the mixture turns frothy.

Next, add the oil and lemon juice. Add the sieved flour and mix well but do not overmix.

Fold in the blueberries gently, you do not want to crush them. Leave a few blueberries to be added on top of the batter.

Bake for 20 minutes or until a toothpick inserted comes out clean.
