You can use any plant milk of your choice, but we found that soy was the one that mimicked the taste of cow’s milk the best. Oat milk also makes a yummy arroz con leche. You can add fresh fruit, orange zest, dried fruit, nutmeg, and even vegan condensed milk. I decided to use long-grain rice because it’s what is most accessible, but using short grain rice will give a creamier result.
