I’m thinking about using playdough as an object lesson in an upcoming teaching session, so I was googling it and found a recipe billed as “The Perfect Home Made Play Dough Recipe!” Although the first (and second) time the author tried the recipe, she thought that “cream of tartar” was tartar sauce. Which, as you can imagine, did not have stellar results!
I haven’t tried this, but if I do, I’ll update with the results.
