In a small bowl, combine the raisins and bourbon. Set aside.
In a medium saucepan, combine milk, water, rice, sugar, cinnamon stick, salt, grated nutmeg, and ground cloves. Bring to a boil over medium-high heat. Reduce the heat so that the liquid is at a simmer and cook, uncovered, until the rice is tender and the liquid is absorbed, about 40-45 minutes. Stir the pot often, especially towards the end.
In a small bowl, whisk together the cream, egg yolks, and vanilla extract. Drain off any extra bourbon from the raisins (unless you want a stronger bourbon flavor in your pudding, in which case you can stir that bourbon right into the mixture along with the raisins). Remove the saucepan from the heat and whisk the cream mixture into the rice. Stir in the raisins.
Serve immediately, or pour into a bowl and place a piece of plastic wrap directly on top of the pudding to prevent a skin from forming. Serve warm or chilled, and garnish with optional toppings.
