Grated apple crisp with oat and Grape-Nuts topping

Grate six apples, unpeeled, into a bowl; stop before reaching the core so no seeds go in.

Squeeze in the juice of one lemon. Add a touch of cinnamon, a very small touch of cornstarch, white sugar and light brown sugar; mix thoroughly and evenly.

Generously butter a baking dish, about a couple tablespoons. Spread the apple mixture in it evenly.

For the topping, combine rolled oats, Grape-Nuts, all purpose flour, white and brown sugar, a pinch of salt and a stick of melted butter; mix slowly until every oat and Grape-Nut is coated.

Spoon the topping evenly over the apples and leave it on top rather than poking it down, so it bakes crispier.

Bake in the center of a 375 degree oven about an hour, until the filling has firmed up and the top is golden brown and crisp.

Let cool until just barely warm; serve with a small scoop of vanilla ice cream and garnish.
