3/4 tsp. salt
1/2 lb. room temperature butter
1 c. sugar
1 3/4 tsp. vanilla
4 eggs
3/4 c. confectioners' sugar

Heat oven to 325 degrees. Butter and flour an 8 x 4 inch loaf pan. Combine flour and salt. Beat butter and granulated sugar until very fluffy, about 5 minutes. Beat in 1 1/2 teaspoon vanilla. Add eggs one by one, beating well after each addition. Beat in flour on low speed until just smooth. Pour batter into pan. Bake 1 hour and 15 minutes. Cool completely before glazing. Stir confectioners' sugar and sour cream over low heat until almost smooth. Remove from heat and stir in 1/4 teaspoon vanilla and 1/2 teaspoon water. Pour on glaze and serve.
