Ask any boba aficionado and they'll tell you that boba is only good for 4 hours after it's first boiled. And to some extent that's true; it's the most chewy, the most tender during that window. But boba can be annoying to make fresh every time you want it, so if you're willing to wiggle a little on quality, you can refrigerate for a few days after you cook it. When you want to use it, microwave until it's soft and squishy, and proceed to enjoy.
