Wholesome, comforting, filling, and just all around delicious. If you have fond memories of rice pudding from your childhood, this might be what you're looking for. If you don't have fond memories, this might be what makes you love rice pudding.
In a large saucepan, combine the 3 cups cooked rice, 3 cups of the milk (save one cup for the next step), the ⅔ cup sugar, and ¼ tsp salt. Cook over medium heat until thick and creamy, about 15-20 minutes.
Stir in remaining 1 cup milk, 2 beaten eggs and 1⅓ cup raisins. Cook for 2 minutes more, stirring constantly.
Remove from heat and stir in 2 tbsp butter, 1 tsp vanilla, and 1 tsp cinnamon, if desired. Serve warm.
