Preheat the oven to 450℉ Lightly dust a baking sheet with flour.
Sift the flour, baking soda, and salt into a large bowl. Stir in the sugar and the dried fruit.
In a separate bowl, beat together the egg and buttermilk. Make a well in the center of the dry ingredients and pour in the liquid mixture. Use one hand stretched like a claw to mix the dough and combine until all is moistened (don't try to knead it or it will be too heavy). The dough will be soft but not too wet and sticky.
Scrape the dough out onto a floured surface and bring together a little more, as needed. Transfer the dough to the floured baking sheet and form a long, flat rectangle, about 1 inch high. Cut into mini scones (triangles) using a pizza cutter or a knife. Pull each scone a little bit away from the others.
Bake 12 to 15 minutes (or until golden and baked through). Let cool a bit, then serve warm with butter and jam (reheat as needed in the microwave).
