In a heavy bottom pot, combine rice and water. Heat to boiling, stirring once or twice. Reduce heat; cover and simmer for 14 minutes, or until all water has been absorbed.
Heat oven to 350 degrees. Blend ½ cup sugar, cornstarch and salt. Beat egg yolks slightly. Add egg yolks and milk to sugar-cornstarch mixture. Whisk to blend. Stir in rice, lemon Juice and raisins. Pour into a 1 ½ quart casserole or baking dish. Place dish in a pan containing boiling water about 1-inch deep.
Bake about 1 ½ hours, stirring occasionally, or until pudding is creamy and most of the liquid is absorbed. Remove pudding from oven, leaving it in the pan of hot water. Sprinkle with cinnamon. Remove from pan when cool. Serve at room temperature.
