Stuffed Mortar Shell

You choose a point within 120 ft or you that you can see, a massive stuffed pasta shell flies from you to the point you chose, exploding in a 20ft radius.
Each creature must make a constitution saving throw. A creature takes 6d8 fire damage on a failed save and is covered in molten cheese until they use an action to remove the cheese, dealing 2d8 fire damage at the start of their turn. On a successful save they take half damage, and are not covered by cheese.
