In a medium skillet, heat 1 teaspoon of the oil over medium-high heat. Add the corn and cook, stirring until starting to caramelize, about 4 minutes. Add the garlic, 1/4 teaspoon of the salt, and the cayenne and cook, stirring, until fragrant and the corn is caramelized, about 1 minute. Remove from the heat and let cool slightly.
In a bowl, combine the corn and the remaining ingredients. Adjust the seasoning, to taste. Serve warm or at room temperature.
Yield: about 1 1/2 cups
