The lamb I cooked was very lean and there was not 2 tablespoons of adequate "drippings" to use for the roux (drippings and flour mixture). I drained all the lamb and reserved for my elderly dogs as a supplement to pour over their food. I then substituted 2 tablespoons of coconut oil (could also use olive oil or butter) in place of "drippings." I used chicken stock, but found 1/2 cup was not quite enough. Toward the end of cooking, I added a few more splashes of stock for a creamier texture. I used dried cranberries in place of raisins. I did not have a lemon to juice/grate, but it still tasted wonderful. I served with plain, buttered potatoes instead of rice. Would also be terrific with couscous or quinoa.
