2 1/2 cups all-purpose flour
2 cups oatmeal
1 cup granulated sugar
1 teaspoon salt
1 tablespoon baking powder
1/2 teaspoon baking soda
1/2 cup very cold unsalted butter, cut into small chunks
1 egg
1/2 cup orange juice
1/4 teaspoon Boyajian orange or tangerine oil or extract
1 cup raisins, plumped and dried

Glaze
Milk
Sugar
Orange zest

Line a large baking sheet with parchment paper. Preheat oven to 425 degrees F.

In a large bowl, place flour, oatmeal, sugar, salt, baking powder, baking soda and mix together. Cut or rub in butter to make a mealy mixture.

Stir in egg and orange juice. Add orange oil or extract. Mix to make a soft dough. Turn out onto a lightly floured board and knead for a few minutes.

Roll or pat out into a thickness of 1/2 inch. Using a serrated cookie cutter, cut into disks or rounds. Brush with milk and sprinkle with sugar and orange zest. Bake until nicely browned about 14 minutes.
