How to Make It
In a bowl, toss the avocado and tomato with 2 tablespoons of the lime juice.
Cut the kernels off the corn. The easiest way to do this is to lay the cobs flat on a cutting board. Remove the kernels by slicing lengthwise with a chef's knife. Add the corn to the avocado and tomato.
Just before serving, add the chiles and cilantro to the salsa and toss gently. Season with salt, pepper and additional lime juice if needed; the salsa should be highly seasoned.
