Step 1

Place your oven rack in the lower-middle section and preheat oven to 400 degrees Fahrenheit.

Step 2

In a bowl, combine 1/3 cup sugar, flour, baking soda, and salt. Add grated butter into the dry ingredients. Use the large holes of a box grater to form big chunks of butter. Use your hands to mix the batter. You'll know it's done when it forms a coarse meal. Add the raisins (or dried currants).

Step 3

In a separate bowl, combine the egg and sour cream. Mix until smooth.

Step 4

Pour the sour cream mixture into the batter until you form dough clumps. With your hands, press the dough against the bowl to form a ball. Take note that the dough might seem sticky and liquid in the beginning, but don't worry, the dough will thicken nicely as you press it.

Step 5

Sprinkle flour onto a clean flat surface. Place the dough on the surface and form into a 7- to 8-inch-circle (about 3/4-inches thick).

Step 6

Sprinkle dough with a teaspoon of sugar. Cut the dough into eight triangles. Place the triangles on a cookie sheet, about 1-inch apart.

Step 7

Bake for 15 to 17 minutes, or until golden. Allow scones to cool for 5 minutes.

Step 8

Enjoy! Can be served warm or at room temperature.
