1/2 cup small-diced red onion
1/2 cup of chopped tomato (one medium tomato)
1/2 cup feta cheese, diced or crumbled
3 tablespoons cider vinegar
3 tablespoons good olive oil
1/2 teaspoon kosher salt
1/2 teaspoon freshly ground black pepper
Large handful of fresh basil leaves, julienned
In a large pot of boiling salted water, cook the corn for 3 minutes until the starchiness is just gone. Drain and immerse it in ice water to stop the cooking and to set the color. When the corn is cool, cut the kernels off the cob, cutting close to the cob.
Toss the kernels in a large bowl with the red onions, tomato, feta, vinegar, olive oil, salt, and pepper. Just before serving, toss in the fresh basil. Taste for seasonings and serve cold or at room temperature.
I used an heirloom tomato from my parents farm but any really ripe fresh tomato will be fine.
