- If using fresh corn, cook the corn and then cut the corn off of the cob before using. Measure out 1 1/2 cups of corn for the recipe.-You may make this ahead and bake when ready to use. Remove from refrigerator about 30-45 minutes before baking. and set on counter. Bake for 20-30 minutes.-You may add chopped peppers, tomatoes that have been seeded, onions (chopped fine), green chilies, and/or other types of grated cheese.-If you cannot find Tillamook Extra Sharp White Cheddar, you may use other brands of cheese. This would also be great with an Extra Sharp (yellow) Cheddar cheese. I would stay with a "sharp" variety of cheese. It will cut the richness of the cream cheese and sour cream combination and add a depth of flavor.
