In a medium pot add the cranberries, the blood orange juice, 1 ½ cups of the granulated sugar and the zest. Boil the cranberries over a medium-low flame until they soften and the mixture becomes sauce like.
Let the cranberry sauce cool.
Preheat the oven to 350 degrees
In a large mixing bowl, mix the cranberry mixture, the apples, ¼ cup of the all-purpose flour, 1 cup of the granulated sugar, ¼ cup of the brown sugar, and the cinnamon. Mix well.
In a separate large mixing bowl, mix in the oats, almonds, the rest ¼ cup of flour, the rest ¼ cup of the brown sugar and the butter. Mix it well
Transfer the filling onto a baking dish
Evenly pour and spread the oat mixture over the filling.
Bake for about fifty minutes, or until the filling becomes soft and bubbling and the oats golden brown
Serve and enjoy (you can eat it straight or with a scoop of your favorite ice cream flavor or whipped cream)
