ham and sun-dried tomato scones

I'm making these scones for dinner tomorrow (to have with roasted red pepper and tomato soup which we bought at Costco and it's REALLY good ... and I don't usually like tomato soup). The first time I made these scones, we ate the entire batch straight out of the oven when they were still warm. We never got around to making the soup because we filled up on just the scones. SO GOOD!

2 cups self-rising flour (if you don't have self-rising flour, here's how to make it)
1 tsp mustard powder
1 tsp paprika
pinch of salt
2 Tbl. margarine, diced
1 Tbl. chopped fresh basil (or 1/2 Tbl. dried basil)
1/2 cup sun-dried tomatoes in oil, drained and chopped
2 ounces strong-flavored ham, chopped
1/2 cup milk

1. Sift the flour, mustard, paprika, and salt.
2. Rub the margarine in with your fingers.
3. Stir in the basil, sun-dried tomatoes, and ham.
4. Pour in enough milk a little at a time to make a soft dough.
5. Turn out the dough onto a floured counter, kneed lightly and roll out into a rectangle. Cut the dough into 2-inch squares and put on a floured baking sheet.
6. Brush the tops of the scones with milk, and sprinkle lightly with paprika.
7. Bake at 400 for 12-15 minutes, until they rise and are a golden brown. Cool on a wire rack.
