6 whole firm ripe peaches, peeled and poached or 2 (16-ounce) cans juice-packed peach halves
Directions
Preheat oven to 400° F. Position rack in center of oven.
Combine 2 Tablespoons of sugar with flour, cream of tartar, baking soda, salt and nutmeg in a food processor. Process briefly to blend. Add butter and pulse until mixture resembles coarse meal. Pour in light cream and pulse just until mixture forms a soft dough. Do not overwork.
Roll dough on a floured surface, using a lightly floured rolling pin, to a 3/4-inch thickness. Use a cookie cutter or shape by hand into circles about 3 to 3 1/2-inches in diameter. Place on cookie sheet and bake until shortcakes are golden brown, about 13-16 minutes. Remove pan from oven and let cool.
Combine heavy cream, vanilla and remaining Tablespoon of sugar in a chilled bowl and beat into soft peaks. Remove pits from peaches, if using fresh peaches, and cut each half in four sections.
Split shortcakes horizontally, and moisten cut sides with a little of the poaching liquid or juice from the can. Arrange peaches on the bottom half of each shortcake. Spoon 2 teaspoons of Raspberry Peach Champagne Jam over peaches, then a large dollop of whipped cream. Place cake lids on top and garnish each with a small dollop of whipped cream.
