Rinse the hominy corn kernels 3 times or until the water runs as clear as possible, then drain.
Place the hominy corn in a bowl, then add 2½ cups of fresh water and let it soak overnight. 📌(If you're short on time or didn’t get a chance to soak the hominy corn, you can use the pressure cooker method or stovetop method below).
Drain the soaking water and transfer the hominy corn to a large pot. Add 5 cups of water and bring to a rapid boil over medium-high heat for 5 minutes
Reduce heat to a simmer and cook until the water reduces and the kernels are tender. If needed, add 1 cup of water at a time and continue simmering until fully softened.
In a small bowl, whisk together flour and 3 tablespoon milk; set aside.
Once the water has reduced and the liquid becomes a thin, gelatinous slurry, stir in the milk and reduce heat to low (should have just a slight bubble).
Add nutmeg, cinnamon, vanilla, and the flour-milk mixture, stirring every few minutes with a wooden spoon for 10-12 minutes, or until the porridge reaches your desired consistency.
Sweeten with condensed milk, remove from heat, and serve warm.
