Turn oven to 350°. Leave husks on the corn and just cut off the strings at the end, if any, and lay on a baking sheet. (If husks look dirty, you can always remove one or two but leave the remaining husks on.)

Cook for 20 minutes on one side, and then carefully flip each ear. Cook another 20 minutes on the other side.

Once done, remove corn from the oven and carefully remove the husks. They should come off very easily, but the corn will be hot.

Lay the corn back on the baking sheet.

Move oven rack to the top and turn broiler to high.

Put corn in and cook for two minutes.

Flip each ear a little and cook another 1-2 minutes. (Be sure to keep an eye on the corn while the broiler is on since some ovens are hotter than others and might be done sooner.) Once they have a good char on part of the sides, remove from the oven.

Let the corn cool off a bit and then carefully cut off the kernels lengthwise from the corn. Place in a bowl and set aside.

In a large pot, cook the ravioli according to the package, which is typically between 3-5 minutes. Once it's done, drain and set aside.

While the tortellini cooks, add about 1½ cups of roasted corn to a blender and pulse until the corn is mostly blended. (Save about ½ cup of the corn to fold in at the end.) If needed, add 1-2 tablespoons of water to help it blend more smoothly.

Add the butter to the same pot you used to cook the ravioli and turn heat to medium. Once it's mostly melted, add the blended corn mixture. Stir well.

Add the cream and turn heat to low. Stir consistently for about a minute.

Add the cooked tortellini and extra corn to the pot, and gently fold into the sauce.

Serve it topped with generous amounts of Cotija cheese and Tajin. Enjoy!
