3Bake the berries in the oven for 30 minutes, stirring once during baking.
4After 30 minutes, remove the berries from the oven and make the biscuits.
5In a medium sized bowl, stir together the flour, baking powder, soda, salt and sugar.
6Cut the butter into the mixture either with a food processor, a mixer or by hand (Tip: try using the large holes of a cheese grater, it works well) the butter should be the size of corn kernels.
7Stir in the buttermilk just until the dry mixture is thoroughly moistened.
