On reflection--take a family. Throw in a couple of sons-in-law. Hope that eventually, their influence will dilute the original recipe. Toss thoroughly. Notice how the stew bubbles with squabbling and laughter. With one female pregnant, one menopausal, and one terminally obstinate, these ingredients will resist blending. That's okay. Do you really want homogenous results? Buy milk. The flavor of family salad, or stew, or anything in more potent if original elements retain their properties.
