Please share your beet knowledge with me...I have never roasted beets but am going to after I pick some up from the farmers market. From what I see, it looks like you wrap them tightly in foil (twice?) and put them in the middle of your oven until tender (approx 1.5 hours). Is this right? I was going to make a salad (arugula, goat cheese, pistachios....) but would love other ideas. How do you store them and for how long? Lastly, what do you do w/the greens? TIA!!!!
