Pumpkin Scones

This is a recipe I tried on the weekend. it is very tasty but a bit hard as a first time at trying to cook proper scones.
It is taken from Lady Flo Bjelke-Petersen's Classic Country Collection.

Ingredients

1 tablespoon butter
1/2 cup sugar
1/4 teaspoon salt
1 egg
2-2 1/4 cup of self raising flour
1 cup mashed pumpkin(cold), it also helps if the pumpkin has been roasted either the night before or earlier that morning, it is also a good excuse to have a roast dinner

Method

Beat together butter, sugar and salt using an electric mixer, a hand whisk will also get the job done. Add egg, then pumpkin. Finally stir in, by hand, sifted flour. Turn onto a floured board and cut. Place on a heated, floured tray and cook on the top shelf of a very hot oven(225° - 250°C), I had it on fan forced at 210°C, for 15-20 minutes.

I find they are nicer still slightly warm because the outside is still quite crunchy.
