At the risk of having everyone respond with, "You've never had THAT before?!" I will say that in the process of making some corn salad last week I squeezed a lemon over some freshly-sauteed corn and was simply delighted with the combination, even before adding the other ingredients.
When you cook corn you think of emphasizing the sweet aspect or deepening the flavor with some butter, but putting something tart on it gave it a different dimension. What a treat.
Anyone else have any other chance food epiphanies you'd like to share?
