This classic dish combines pureed spinach with freshly made cheese in a mildly-spiced creamy sauce. This version includes a little bit of mustard greens for bite. Adapted from Cook's Illustrated Sep/Oct 2012. Note: if you place the colander over a bowl, the whey from the cheese makes very tasty bread. Also note that the serving size reported is incorrect - you are going to lose nearly 3 quarts of whey in the cheese making, so the actual serving size is more like 350gm or 12 oz.
