The only changes I made was using butter rather than margarine, and orange juice instead of lemon.
You Will Need:
3/4 cup margarine (I used butter) softened
1 cup packed brown sugar
1 3/4 cups sifted AP flour
1/2 teaspoon salt
1/2 teaspoon baking soda
1 1/2 cups rolled oats
2 1/2 cups raisins
1/2 cup sugar
2 tablespoons cornstarch (cornflour)
3/4 cup water
3 tablespoons lemon juice (I used orange)
Preheat oven to 400 degrees F. Grease a 9x13 inch baking pan.
Cream margarine and brown sugar until light. Add flour, salt, baking soda, and oats; mix well. Press half the mixture into the pan.
Combine raisins, sugar, cornstarch, water and lemon juice in a saucepan; mix well. Cook over medium heat, stirring until it thickens-about 5 minutes. Remove from heat, cool slightly, and spread atop first layer. Press remaining mixture over the raisins.
Bake 20-30 minutes (mine took 25) and cool in pan. Cut into squares. The recipe claims you'll get 36 squares...if you're a miser. Unless you're the type of person that serves their sweets in centimeters, go ahead and cut them generously.
