"When making scones, Granny always went to the open outer door with the bowl of flour and, lifting the meal high in her hand, let it trickle through her fingers so that it was thoroughly aerated, giving a delightfully light scone which kept fresh for days."

It seems every baker has their own method of making scones for Paul Hollywood in How to Bake
(from where that picture comes) says he uses bread flour to give "strength and structure. As long as you don't overwork the dough, the scones will be fluffy and light. To achieve this, I use a technique called 'chaffing' [putting the wet and sticky mixture on a floured board, sprinkling the rest of the flour on top, then folding the dough in half, turning it 90 degrees and repeating, gradually incorporating the last of the flour and adding air] which gently brings the dough together without developing the gluten in the flour too much."
In The Scots Kitchen
, F. Marian McNeill devotes a chapter to bannocks, scones and teabreads, and among many recipes gives that for Mrs. Macnab's Scones. "Mrs. Macnab was the wife of a farmer who lived near Ballater. Such was her reputation as a baker that King Frederick of Prussia and other distinguished guests at Balmoral used frequently to go over and have tea with her. It is not possible to impart Mrs. Macnab's lightness of touch, or the wine-like air of these regions, which doubtless contributed to her visitors' enjoyment; but here, at least, is the recipe for her celebrated scones:
Mix thoroughly a pound of flour, a teaspoonful of salt, a small teaspoonful of bicarbonate of soda and two small teaspoonfuls of cream of tartar. Rub in two ounces of butter. Stir in gradually a beaten egg and half a pint of buttermilk. Turn out the dough on a floured board, flour the top, and knead with the hand as little as possible. Cut off pieces of dough and flatten them with the knuckles, but do not roll out at all. Prick with a fork and cut into quarters. Bake in a pretty quick oven for from ten to fifteen minutes. The secret of success lies in not working the dough with the hands except just once kneading it."
One final word on the subject, and this on the word itself, though Miss McNeill says its etymology is uncertain; but interestingly she mentions that it first appears in the sixteenth century in Gavin Douglas's translation of the seventh book of the Aeneid where, at a feast at the mouth of the Tiber,
"The flour sconnis weir set in by and by With other messis."
