Preheat oven to 350º F.
Pour 2 cups hot Earl Grey tea over raisins and set aside to soak.
In medium bowl, sift together flour, sugar, baking powder, salt, and spices. Cut in butter until blended thoroughly.
Add tea with raisins and stir until smooth.
Pour into loaf pan and bake for 50-60 minutes, when a tester inserted in the center of the loaf comes out clean.
Allow to cool for 10 minutes, then remove loaf from pan. Stir together remaining tea with icing sugar and brush over loaf.
Serve warm with sweet butter. Loaf will keep for 3 days wrapped well and at room temperature.
