Place raisins with Black Currant (or Black Cherry) Dark Balsamic Vinegar in a bowl and let soak for a least one hour.
Combine all dry ingredients into a bowl.
Add the cubed butter and Blood Orange EVOO to the bowl. Mix it all up with your hands, breaking the butter up into tiny pieces, until fully incorporated.
In a small bowl, whisk the egg with the buttermilk.
Add buttermilk mixture and the drained raisins to the flour mixture.
On a floured surface, knead the dough with your hands, adding additional flour as needed. Form the dough into the shape of a round loaf.
Place dough on a baking sheet lined with greased parchment paper.
Cut an ‘X’ into the top of the loaf. Sprinkle with raw sugar. Bake in oven for 30-35 minutes for 400°F (or until toothpick comes out clean). The loaf should sound hollow when you tap it.
