<<Disclaimer: Verify this information before applying it to your situation.>> For several years, I have made this cobbler in July, when the blueberries are ripe on the bushes and there are fresh local peaches at the farmer's market. Since my husband was diagnosed last November, I decided to give it a whirl with gf flours. It is as delicious as it always was. This topping is fluffy and cake-like, not like the biscuit-like toppings on some cobblers. Enjoy! Kathy Pittsburgh, PA Peach Blueberry Cobbler Topping: 1 cup flour (I used four flour blend plus 1/4 tsp. xanthan gum) 1/2 cup sugar 1-1/2 tsp. baking powder 1/2 cup milk 1/4 cup margarine Filling: 1/4 cup brown sugar 1 Tblsp. cornstarch 1/2 cup cold water 3 cups sliced peaches (about 5 medium) 1 cup blueberries 1 Tblsp. margarine 1 Tblsp. lemon juice 2 Tblsp. coarse sugar (or just regular sugar) 1/4 tsp. cinnamon Make topping: Stir flour, sugar, and baking powder together. Add milk and margarine all at once. Stir with a whisk until smooth. Set aside. Prepare filling: Combine brown sugar, cornstarch and water in saucepan. Add peaches and blueberries. Cook and stir over medium heat until thickened and bubbly. Remove from heat; add margarine and lemon juice; stir until margarine melts. Pour filling into an ungreased 8" square pan. Spoon topping in mounds over hot fruit; spread evenly over. Sprinkle with coarse sugar and cinnamon. Place on a shallow baking pan (because it may bubble over) and bake at 350 degrees until bubbly and a toothpick inserted in the topping comes out clean. This is good either warm or cold.
