Place the corn, cheese, melted butter and salt in the food processor and mix until the corn is pureed.
Transfer mixture to a bowl and let it sit for 15 minutes.
For each bollo, arrange 2 corn husks on a work surface. Divide the mixture evenly and place in the center of the husks.
Roll the corn husks so that the filling is completely enclosed. Twist and tie the ends.
In large pot place about 2 cups of water. Place the pot on the stove over high heat until the water is boiling, reduce the heat to a simmer and cook for about 40 to 45 minutes.
