How much Tapioca will it take for a Sour cherry fruit pie?

For a sour cherry fruit pie, you'll typically need about 2 to 4 tablespoons of tapioca starch or tapioca pearls, depending on the recipe and the amount of fruit used. This helps to thicken the filling and absorb excess moisture. Adjust the amount based on the tartness of the cherries and personal preference for thickness. Always consult your specific recipe for the best results.
