Preheat oven: Preheat oven to 350°F. Grease a baking sheet.
Mix dough: Thoroughly combine flours, sugar, salt, baking powder, baking soda, and caraway seeds. With a pastry blender, cut in butter until finely blended and stir in minced raisins.
Make buttermilk: Make the buttermilk by adding 1 1/2 Tablespoons apple cider vinegar into a 2 cup liquid measuring cup. Add almond milk until you reach 1 1/2 cups of liquid.
Add wet ingredients: In a small bowl, beat the egg and the almond milk mixture. Add to flour mixture. Gently stir and fold until just combined. Form dough into a rounded, disk-shaped loaf a few inches thick and 7 to 8 inches wide.
Bake: Place on prepared baking sheet. Using a sharp knife, mark top of loaf decoratively with 1/2-inch deep knife slashes. Bake on the middle oven rack for 50 - 60 minutes or until a knife or toothpick inserted in center comes out clean. Remove to a wire rack and cool completely.
