I have cooked this recipe countless times. If you notice, I have upped the amount of tapioca that is called for. In the original recipe it calls for 3 tablespoons, in the tapioca package is calls for 1/4 cup per 9 inch fruit pie. I edited the recipe to use 1/4 cup per pie and the pie came out with a nice filling that was not too watery and loose. It was perfect. I updated the recipe to use prepared pie crusts, much easier that making them from scratch.
Very lemony, and very good. I cooked it on the outdoor grill. I would modify the recipe to marinate the chicken in the lemon mixture, then grill it while heating the marinade back up in a pot so you can use it as a sauce and not worry about contaminating food.
