The wonderful flavor and aroma of fresh ginger shines through in this simple yet delicious cake -- and is a great reason to keep a knob on hand (just wrap it in plastic wrap and keep in the vegetabale crisper). You can peel the ginger with a spoon (or a paring knife) before grating or mincing. Almonds and cinnamon round out the flavors here. Serve the cake warm or at room temperature, on its own or with a dollop of whipped cream on top.
