Mix all ingredients except potatos in glass baking dish, whisk together, then add potatoes. Put in oven at 350 degrees for 1 hr. After 1 hr remove liquid and continue roasting potatoes for 45 minutes. Remove from oven and put on plate, pour reserved heated liquid over potatoes. My personal opinion is this is too long a process for potatoes and is not energy efficient. Next time I will cook on stovetop.
