Preheat oven to 425 degrees Fahrenheit.
Make a 9" pie crust and put in pie plate. Sprinkle crust with 1 tablespoon flour.
Mix together sour cream, flour, sugar, and almond extract. Stir in peaches (drain if using canned). Pour peach/sour cream mixture into unbaked pie crust and sprinkle brown sugar over top (i used about 1-2 tablespoon compared to the 1/4 cup, doesn't seem to matter that much).
Bake at 425 degrees for 20 minutes, then lower temp to 350 degrees and continue baking for 35 minutes.
This recipe might sound weird but it is soooooo good!
