From Grape Juice to Crystals
Cream of tartar is a byproduct of winemaking. While the grape juice is fermenting, it precipitates out of the wine and collects on the sides of the containers. Grape juice, if chilled or left to stand, can also sometimes evaporate and collect in solid crystals.
The Many Uses For Cream of Tartar
When the crystals are purified, they form cream of tartar, which is acidic. It is often used in baking for leavening and for stabilizing. Because it comes from a natural source (it’s basically evaporated grape juice) there’s no reason not to include cream of tartar in your Paleo diet.
If you’re trying to bake a Paleo dessert, cream of tartar can be used to help get that doughy consistency. The Paleo Mom has a few tips on how to do just that.
