Butter and salt aim to enhance corn's rich taste, but lemon juice is an ingredient that really makes the vegetable stand out. The citrus adds a zesty quality to corn, brightening the juicy kernels. Lemon's tart taste has an undercurrent of sweetness to it, so it doesn't reduce corn's honeyed flavor. Instead, it enhances it while providing the veggie with an acidic boost.
In fact, sometimes I just opt for the fastest method ( boiling corn in a pot of seasoned water) so I can bite into a crunchy, sweet and salty ear of corn as quickly as possible. Unfortunately, cooking corn on the stovetop, especially when using frozen corn, increases the risk of soggy corn on the cob that isn't very flavorful.
