Step 1: Cook the Rice - In a medium saucepan, bring 1½ cups of water to a boil. Add the rice, lower the heat, and simmer until the water is fully absorbed (10-12 minutes). Stir occasionally to prevent sticking.
Step 2: Sweeten & Add Soy Milk - Once the rice absorbs the water, stir in the sugar and a pinch of salt. Then, pour in the soy milk and bring it to a gentle simmer over medium-low heat. Cook for another 15-20 minutes, stirring frequently, until the pudding thickens.
Step 3: Add Flavor - Once the rice pudding reaches a creamy consistency, stir in the vanilla extract, cinnamon, lemon zest, and lemon juice. Let it cook for another 2 minutes to fully incorporate the flavors.
Step 4: Serve & Enjoy! - Remove from heat and let the pudding sit for a few minutes to thicken further. Serve warm or chilled, sprinkled with extra cinnamon on top.
