In a small glass bowl whisk together all of the salad dressing ingredients.
Refrigerate until ready to use.
Bring a large pot with salted water to a rolling boil.
Add in corn cobs and simmer uncovered for about 3-4 minutes just until corn color deepens.
Immediately place corn cobs into a cold ice bath of water to stop the cooking process. Remove from ice bath, then set cobs on towels to air dry a bit.
Place corn on a cutting board, then slice the corn kernals from the cob.
In a large bowl combine corn with avocado, tomatoes, cucumber, red onion, and basil.
Just before serving, drizzle with your homemade tangy dressing and very gently toss to combine.
