Preheat oven to 180 degrees Celsius.

Grease 9-inch pie dish with butter and dust with 1 tablespoon of sugar. Set aside.

Mix remaining sugar, flour, salt, ginger, garam masala, eggs, milk, heavy cream and vanilla until mixture is frothy.

Arrange blueberries at the bottom of the dish. Pour batter over them.

Bake for 40-50 minutes, rotating dish halfway. You know it's done when you insert a knife into the centre and it comes out clean.

Serve warm or at room temperature dusted with powder sugar and with a little bit of whipped cream if you like.
