I adore Grape-Nuts so I'd give the mousse the benefit of the doubt. However, I actually own a bottle of glycerine (it was falsely represented to me that you can use it to turn castile soap into something that will acceptably wash dishes) and ewww, I wouldn't EAT it. BTW in the US "Miracle Whip," a cheaper substitute for mayonnaise, is essentially boiled dressing. But it doesn't have glycerine in it.
