Stir in the grapes, cover again with foil, and bake for 10 minutes more. Remove the pan from the oven and carefully remove the foil. (You can let the mixture cool, cover, and refrigerate it for up to a day prior to proceeding with the recipe. Easier for entertaining and more melded flavors.)☞ TESTER TIP: Be very careful of the steam when lifting the foil off the roasting pan! Stand back and use an oven mitt or towel to remove the foil.
