1In a heavy-bottomed saucepan, combine the short grain rice, whole milk, piloncillo, Mexican cinnamon stick, and lime zest. Bring to a gentle simmer over medium heat, stirring occasionally to prevent sticking.
2Reduce heat to low and continue to cook, stirring frequently, until the short grain rice is tender and the mixture has thickened to a creamy pudding consistency, about 30-40 minutes.
