Preheat the oven to 375 degrees F. Butter the inside of a medium baking dish. In a large bowl, peel then slice the peaches into fairly thick wedges. Add the lemon zest, half of the honey, 1/2 cup brown sugar, and a pinch of salt and combine well. At this point you can mix in the berries. Allow the mixture to sit for 5 – 10 minutes to allow the fruit to release its juices. Pour reduced peach juice over fruit, for amazing flavor collect most of the juice and put it in a small sauce pan and cook on low-medium until the juice is reduced to about half. Remove from stove and add the cinnamon and stir. Pour this mixture over the fruit. Gently mix in 2 tablespoons of flour, and then put the fruit into the prepared dish. At this point add the cinnamon and 2 tablespoons of flour, and then put the fruit into the prepared dish and set aside.Combine 1 1/2 cups flour, baking powder, the other half of the honey, 1/2 cup brown sugar, salt, nuts, oatmeal, and the cold, diced butter, using an electric mixer or your hands, combine until the mixture is crumbly. Sprinkle over the fruit. Bake for 1 hour, until the top is a nice golden brown color, crisp and the juices are bubbly.You can serve immediately, or let the crisp remain on the counter if you plan to serve it the same day. Store leftovers in the refrigerator. Just reheat until warm. Serve with dollops of vanilla ice cream or whipped cream. This makes a wonderful dessert or even a rich breakfast with a cup of coffee next day.Absolutely incredible!!!
