Portuguese Rice Pudding

1 cup rice
1 cup water
½ tsp salt
5-1/2 cups milk
1 large egg, beaten
1 cup sugar
cinnamon

In a heavy pot (preferably not Teflon coated), boil rice and water over high heat, stirring constantly, until water is absorbed. Lower heat to medium and add salt and 2 cups milk, stirring well and cook for 15 minutes. Add another 2 cups milk, stirring well, and cook for 15 minutes. Add another 2 cups milk, stirring well before and after. Repeat this process 15 minutes later with remaining 1-1/2 cups milk. Stir constantly for an additional 20 minutes, then blend in beaten egg, and cook for two minutes. Add sugar, stir well, and cook for two more minutes. Pour into a medium-sized bowl, dust with cinnamon, and cool or refrigerate before serving.
