Mom's Very Berry Pie

Mom's Very Berry Pie

1 quart (2 lbs.) fresh or frozen berries (I use a triple berry mix)
1 TB. lemon juice and ½ tsp. minced lemon rind
1 cup sugar
2 ½ TBs. tapioca (Can also use 3 TBs. cornstarch in juice or clear gel)

Combine above ingredients. Pour into a 9 inch unbaked pie crust. Dot top with 2 TBs. butter. Put on top crust. Cut slits in the top for the steam to escape. Bake 45-50 minutes at 375 degrees down low in the oven. May need to cover edges to keep from burning.
