Cook the corn till just barely done. Parboil it or wrap each ear in wax paper and microwave 2 minutes/ear. (4 ears = 8 minutes.)
When the corn is cool enough to touch, cut it off the cob and put the cut corn in a bowl.
Put everything except the corn and parmesan cheese into a food processor and blast until it forms a paste. If you don't have a food processor, just mince everything.
Add the spicy paste and the parmesan cheese to the cooked corn.
Chill at least 30 minutes. Garnish with fresh basil before serving
