Put gooseberries in sauce pan and slightly cook. Thoroughly mix flour and sugar and add to the slightly cooled berries. Pour contents of sauce pan in pie crust and sport with dabs of butter. Add top crust, punch a few holes for vent and bake in 375 degree oven for about 45 minutes. I find it helpful to rim the crust with strips of foil to keep the rim from overbaking. Also, top crust can be omitted and a Dutch apple topping substituted. Mighty good.
