Cream of tartar is actually a byproduct of winemaking. It’s the crystalline residue that forms on the inside of wine barrels. Fancy, right?
Chemically, it’s potassium bitartrate. And it’s a bit of a kitchen miracle worker. It stabilizes egg whites, prevents sugar crystals from ruining your caramel, and adds a subtle tang to snickerdoodles.
Think of it as the quiet, reliable friend who never asks for the spotlight but makes everything better. Like a bouncer for your batter.
