To achieve the sweet flavor and soft texture of this dulce Spanish dessert, most prefer to use short grain white rice. While brown rice will result in a healthier version, the consistency might be slightly altered. Long grain rice will work as well, but it has a lower starch content than short grain rice, so your rice pudding may be less creamy.For extra flavor in this arroz con leche recipe, you can also add a teaspoon of vanilla extract. Some recipes also call for a 1/2 cup sugar for added sweetness!
