Pennsylvania Dutch Sour Cream-Apple Pie

Submitted by ratherbeswimmin

"Very rich. When an apple pie is cooked in thick custard, expect the apples to stay a little on the firm side. They won’t get as soft as they do in an apple pie made without a custard."

11. Continue baking for about 20 minutes or until golden brown.
12. Transfer pie to wire rack to cool for at least 2 hours before serving;
13. You may serve this pie chilled, so after it is thoroughly cooled, cover with loosely tented foil and refrigerate at least 2 hours.
