The less time you can spend working the dough, the better. After cutting in the butter to the flour and adding cream, a crumbly dough will form. All you need to do is transfer it to a lightly floured work surface and gently bring it together into a ball. You should only need to knead 3 to 5 times.
We just use our fingers to lightly pat and push the dough together then flatten it into a disc. From there, we cut the disc into eight triangles. (You could also use a biscuit cutter).
