Preheat oven to 350° F. Place the peaches in the bottom of a 9 X 9-inch baking dish. Sprinkle with the lemon juice and ½ tablespoon of cinnamon. In a mixing bowl, combine the butter, the rest of the cinnamon, flour and brown sugar (and pecans, if using.) Crumble on top of the fruit and bake for 30 minutes, or until brown and bubbly.
For a special occasion, top with Peach Brandy Sauce, a little vanilla ice cream, or whipping cream.
Peach Brandy Sauce
Puree the peaches. Combine with brandy in a saucepan, and simmer 10 minutes over a low heat, stirring constantly.
