Preheat oven to 350. Butter a 1 1/2 quart glass baking dish. Prepare another pan large enough to hold the baking dish plus some water. In a mixing bowl combine 3/4 cup sugar, the salt and flour, mix well. Add the melted butter, lemon juice, lemon zest, and egg yolks. Blend well. Stir in the buttermilk. In another bowl, beat egg whites with remaining 1/3 cup sugar until stiff but not flaky. Fold beaten egg whites into lemon mixture. Pour batter into baking dish. Place baking dish into second pan. Pour in hot water to come half way up the sides of the cake baking dish. Bake about 40 minutes until top is golden brown. Serve warm or cold with berries.
