Mix flour, baking powder, sugar and salt in a large bowl.
Cut butter into small cubes and blend with a pastry blender until it resembles
oatmeal (or small peas, if you don't like oatmeal).
Add the orange zest and
Slowly and gradually add the cream while mixing with a fork.
As soon as the flour starts to come together into a dough, remove from the bowl
and form into a ball. Place on a lightly floured surface and knead gently four or
five times. Then shape with your hands (or a rolling pin) into an 8 x 10-inch rectangle.
Cut the rectangle lengthwise into two 4 x 10-inch rectangles. Cut each of those
into 6 or 7 triangles and place on an ungreased baking sheet.
Bake for 20-25 minutes until golden brown.
Serve warm with softened butter, jam, creme fraiche or just as they are!
