I love the corn salsa at chipotle too, and after I emailed chipotle and they said they wouldn't share the recipe, I made several recipes and this one I love and is close. I hope you enjoy.

CORN SALSA (LIKE CHIPOTLE'S)

2 ears very fresh corn( i used canned too, i like it better)
2 vine-ripened tomatoes
1 small red onion, diced
3/4 cup diced red bell pepper
2 jalapeno chiles, minced (save some of the seeds)
2 teaspoons pureed canned chipotle chiles
2 limes, juice of
1 tablespoon olive oil
1/4 cup chopped fresh cilantro
Salt to taste

Remove the husks and silk from the corn and rinse the ears. Simmer the corn in rapidly boiling water for 2 minutes; drain and immediately plunge the ears into a bowl of cold water to stop the cooking. Cut the kernels off the cobs. Cut the tomatoes into the same size dice as the onions and bell peppers.

Combine the corn with the diced and minced vegetables; sprinkle in the reserved jalapeno seeds. Stir in the chipotle puree, lime juice, olive oil, cilantro and salt.
