Ginger Scones with Cardamom

This recipe is adapted from Joan Nathan's cookbook, New American Cooking. I brought them as a treat to Eli's graduation in New Haven last weekend.

Makes 12 scones

Ingredients:
2 1/4 cups all-purpose flour
3/4 cups quick oats
2 teaspoons baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
3/4 teaspoon cardamom pods, crushed and inner seeds ground (or 3/4 t ground cardamom)
dash of cinnamon
1/2 cup (1 stick) unsalted butter, cut into small pieces
1/4 cup crystallized ginger, chopped in 1/4-inch pieces
3/4 cup sour cream or yogurt
1/2 cup sugar
4 teaspoons sugar
2 large eggs

Directions
1. Preheat oven to 350 degrees. Grease two baking sheets and set aside.

2. Place the flour, oats, baking powder, baking soda, and salt in a large bowl and mix. Sift ground cardamom seeds and cinnamon into mixture; stir to combine. Add butter and mix until crumbly (use your fingertips).

3. Add ginger, sour cream or yogurt, 1/2 cup sugar, and 1 egg. Mix, blend, or pulse, just until combined; do not overmix.

4. Form 1/4 cup dough into a ball or use a large ice cream scoop, and place dough on prepared baking sheet. Repeat with remaining dough, spacing scones about 2 inches apart.

5. In a small bowl, mix together remaining egg with a dash of water. Brush scones with egg mixture and sprinkle evenly with remaining 4 teaspoons sugar. Bake until golden brown, 15 to 20 minutes.
