I use whole kernel corn for this recipe, and do not recommend that you puree them. I did try preparing corn cheese balls with pureed and creamed corn and the results were not good. If using canned corn, make sure to use cooked corn and not raw corn. Do not use either frozen or fresh raw corn kernels as these will explode or burst in the oil. Always make sure to cook the corn kernels thoroughly by steaming or boiling before using in the recipe.
