To clean beetroot, first trim off the leaves and wash the beetroot thoroughly under cold water. You can then boil, steam, roast, or grill the beetroot.  To boil, place the beetroot in a pot of salted boiling water and simmer until tender, usually about 30-40 minutes, depending on the size of the beetroot.  For steaming, place the beetroot in a steamer basket over a pot of boiling water and steam until tender, usually about 20-30 minutes.  To roast, wrap the beetroot in foil and roast in the oven at 200°C (400°F) for about 45-60 minutes or until tender. Once cooked, the skin of the beetroot can be easily peeled off with a knife or simply rubbed off with your hands.
