Please enter the URL (displayed in the text-based version only. In the GUI version the user puts the information into a TextField)

Directions:

Preheat oven to 425 degrees F (220 degrees C). Melt the butter in a saucepan. Stir in flour to form a paste. Add water, white sugar and brown sugar, and bring to a boil. Reduce temperature and let simmer.

Gently pour the sugar and butter liquid  over the crust. Pour slowly so that it does not run off.

Bake 15 minutes  in the preheated oven. Reduce the temperature  to 350 degrees F (175 degrees C).

Continue  baking for 35 to 45 minutes,  until apples are soft.
