In a large bowl combine 1 pint of the strawberries and the granulated sugar and with a potato masher mash the berries gently until they release their juices, being careful not to crush them to a pulp. Add the remaining 1/2 pint of berries. Let the mixture stand at room temperature, stirring occasionally, for 1 hour.
In a bowl beat the heavy cream with the sour cream and the confectioners' sugar until it holds a soft shape and beat in the vanilla. Split the biscuits horizontally with a fork, arrange the bottom halves on 4 plates, and spoon the strawberry mixture over them. Top the strawberry mixture with some of the whipped cream and arrange the biscuit tops on the cream. Serve the remaining cream separately.
Into a bowl sift together the flour, baking powder, sugar, and salt, add the cream, and stir the mixture until it just forms a dough. Gather the dough into a ball, knead it gently 6 times on a lightly floured surface, and roll or pat it out 1/2-inch thick. Cut out as many rounds as possible with a 2 1/2-inch round cutter dipped in flour and transfer them to an ungreased baking sheet. Gather the scraps, reroll the dough, and cut out more rounds in the same manner until they are 10 in all. Brush the tops of the rounds with the milk and bake the biscuits in a preheated 425 degree oven for 15 minutes, or until they are pale golden. Transfer the biscuits to a rack and let them cool for 5 minutes.
Yield: 10 biscuits
