Lucinda's Apple Crisp
For a pear version of this dish, use four or five Bosc pears. Switch lemon juice for lime, omit the cinnamon, and double the ginger in the topping. For peaches or nectarines, peel and slice 6 pieces of fruit, and toss in orange juice instead of lemon. Add 1 teaspoon of orange zest to the topping and increase the flour to 1/4 cup.
