Method:
Pre-heat oven to 350°F (180°C)
In a bowl, whisk together 3/4 of the buttermilk, eggs, egg white and vanilla.

In another bowl mix together flour, sugar, baking powder, ground ginger, cinnamon, baking soda, cloves, nutmeg and salt. Place into a stand mixer and beat in butter and remaining buttermilk; then beat at medium-high speed for 2 minutes. Slowly beat in egg mixture, a little at a time, beating between each addition. Fold in crystallized ginger.

Pour into a greased 10" (3 L) Bundt pan; run a knife through the batter to remove any air bubbles. Bake about 40 minutes or until cake tester comes out clean. Let cool in pan on a rack for 10 minutes. Invert onto rack and let cool completely.

Caramel Sauce: In a saucepan, bring sugar, butter and cream to boil stirring constantly. Boil until sugar is dissolved, about 2 minutes.
Pour over cake just before you serve.
