3While stew is simmering, trim beets, leaving root and 1 inch stem on each, scrub with a brush. Place in a medium saucepan , and cover with water; bring to a boil. Cover, reduce heat, and simmer 35 minutes or until tender. Drain, rinse with cool water. Drain; cool. Leave root and 1 inch stem on each beet; rub off skins. Cut each beet into 6 wedges.
