Preheat oven to 375 degrees.

In mixing bowl with paddle attachment, combine flour, sugar, baking soda & salt. Add diced butter and mix on low until butter is incorporated.

In a separate bowl, beat egg, buttermilk and orange zest and mix together. Pour into flour mixture. Add raisins and currants. Mix until all come together in a dough ball.

Dump dough onto floured surface and knead 4-5 times until dough comes together and can be shaped into a mound. Place dough onto a tray lined with parchment paper. Cut a shallow ‘X’ on top of dough with a knife.

Bake 45-50 minutes, or until toothpick tests clean. Bread will sound hollow when tapped.

Cool on rack.

Serve warm with butter or jam or both!
