Naples Grape Pie

Directions

1. 1
   ["Pop the skins off the grapes by pinching them at the end opposite the stem; set them aside.", "Put the pulp (without water) into a heavy pan, bring it to a boil, and let it boil 5 to 6 minutes; put it through a colander or food mill to remove the seeds.", "Pour the hot pulp over the skins and let the mixture sit for 5 hours (Irene says this colors the pulp and makes it pretty).", "Add the sugar and tapioca, then pour the mixture into the pie crust and dot with butter.", "Put on the top crust (Irene uses a\"floating\"" top crust-a circle of dough slightly smaller than the top of the pie-because it is easier than crimping top and bottom together and it also makes a pretty purple ring around the edge).""
