Add 2 tablespoons of milk, mix until it resembles small pebbles. Adding more milk if needed.
Heat a small frying pan on low to medium-low heat. Add ¾ cup of mbejú mixture, and with the help of a spatula, bring the little pieces around the pan together, pressing them with the rest of the mbejú mixture.
