Pumpkin Arroz con Leche

Combine 2 cups water, rice, cinnamon stick, cloves and star anise in a sauté pan. Soak for at least 1 hour. Once finished soaking, place pan over medium heat; add remaining water (from soaking) and salt. Bring to a boil for 3 minutes then remove spices with tongs and discard. Add evaporated milk, sugar, pumpkin and raisins. Stir until pumpkin mixes in completely. Reduce heat to medium-low and cook for 20 minutes, stirring every 5-7 minutes. Stir in butter. Remove from heat, cool for 15 minutes and serve. Sprinkle with ground cinnamon for garnish.
