Add the onions, garlic, carrots and celery and cook until lightly golden brown. Return the shanks to the pot. Add the wine, chicken stock and cranberry juice and season with salt and pepper. Bake covered in the oven for 1 1/2 hours, or until the shanks are very tender. Remove the shanks from the pot and strain the sauce mixture into a clean small saucepan. Over medium heat, swirl in the butter, currants and almonds and season with salt and pepper, to taste.;
