Preheat oven to 375F. Spray an 8x8 baking dish with oil and set aside.
First, peel and thinly slice apples and pears and add to a large bowl. Add orange juice, orange zest, lemon juice, lemon zest, molasses, sugar, flour, cinnamon, nutmeg and ginger. Toss to coat everything well, then transfer to the prepared baking dish.
Next, make the crisp topping. In a medium bowl, mix together the flour, oats, sugar, cinnamon, nutmeg and pecans. Add the cold butter pieces and use your fingers to incorporate the butter into the dry ingredients—this should resemble coarse, wet sand.
Spread the crisp topping evenly over the pears and apples. Cover with foil and bake for 35 to 40 minutes, removing the foil at the 20 minute mark.
Allow crisp to cool for 10 minutes before serving warm with vanilla ice cream.
