1Cook corn in a large pot of lightly salted boiling water until crisp-tender, about 4 minutes. Using a slotted spoon, transfer to a bowl of ice water. Let cool, drain.
2Layer corn, garlic, chiles, and peppercorns in a 4 quart glass or ceramic jar.
Stir 5 1/2 tablespoons salt and 2 quarts of water in a large bowl until the salt is dissolved. Pour over the corn mixture.
3Place several plates or small bowls over vegetables to keep them submerged by at least 2 inches. Cover the jar with plastic wrap or a lid and let stand in a dark, cool place such as a cellar, closet, or pantry at room temperature (68 to 70 degrees is ideal) for 4 days to pickle the corn. You can let it sit for 1-2 more days if wanted and then serve, or refrigerate for up to 3 weeks.
