Here’s the thing: life is too short to stress about a $.49 jar of white powder. Using expired cream of tartar is perfectly safe, and in most cases, it’ll work okay for your average Tuesday night cookies. Your family won’t even notice the difference unless you tell them.
So go ahead, use that dusty jar. Embrace the imperfection. If your meringue doesn’t tower like a cloud, just call it “rustic” and add extra whipped cream. That’s what real home cooks do. And if you end up with a flat pancake pavlova like me, you’ll have a story to tell—and that’s worth more than any perfect dessert.
Now go bake something, even if your cream of tartar is a little past its prime. You’ve got this.
