Preheat oven to 450°F. Line a baking sheet with parchment paper. Set aside.
In a large mixing bowl, use a whisk to sift together flour, baking powder, salt, and baking soda.
Add grated butter, mix until evenly distributed.
To the bowl add sausage, cheese and chives, mix well.
Make a well in the center adding buttermilk. Mix thoroughly. Turn out onto a lightly floured non-stick surface. Turn a couple of times to bring together and lightly coat with flour.
Press into roughly a 9 x 9 inch square around 1-inch thick. Use a sharp knife dipped in flour to cut into 12 even squares.
Place squares side by side on baking sheet. Brush tops with melted butter or cream.
Bake for 18-20 minutes or until golden and puffed.
Serve immediately brushed with additional butter, if desired.
