This recipe came to The Times from Hayden Hall, the chef and an owner of Oxbow Restaurant in Clarksdale, Miss. Red pepper flakes and apple cider vinegar give the greens a sharp edge, and ham hock gives them even more succulence.
03Add 2 cups water, the apple cider vinegar, the ham hock and the collard greens; stir to combine. Cover pot, raise heat to high, and bring to a rolling boil. Stir collards thoroughly to incorporate flavors, then reduce heat to low and simmer, stirring every 30 minutes, until collards reach desired tenderness, at least 30 minutes but preferably up to 2 hours. Remove ham hock; pull off and chop meat and return to pan, or discard if desired. Season with salt and pepper.
