Combine sugar, water, raisins, butter, cloves and salt; bring to a boil, stirring occasionally. Boil for 1 minutes, then remove from heat. Mix in flour and baking soda (dissolved in 1 tbsp of water). Spread into lightly buttered 11 1/2" X 17 1/2" pan. Bake at 350 degrees for 15 minutes or until middle puffs slightly. Cool, frost, cut into bars.
Frosting:
Combine and beat until smooth; adding enough liquid to make icing easy to spread thinly over bars.
