I pulled up a lot of dandelion plants and roasted the roots. You wash them off real good, cut them in smaller pieces and dry them off a little and throw them in the oven at 3:50 for about 30 minutes or so then I stirred them around a little bit and then just kept cooking at about 10 to 15 minute intervals until they were crispy and totally dried out. I think all in all it probably took about an hour. You can add this to your coffee grounds for an interesting cup of coffee. I think it has a nice flavor kind of reminds me of the chicory coffee they served down in New Orleans.
