Boil the Water: Fill a large pot with enough water to fully submerge the corn. Bring it to a rolling boil over high heat.
Sweeten & Submerge: Stir in 1 tablespoon of sugar into the boiling water. Carefully drop the shucked corn into the pot and lower the heat to medium.
Cook Temporarily: Cook the corn for exactly 5 to 7 minutes until the kernels turn bright yellow and tender. Do not over-boil.
Prepare Garlic Butter: While the corn is boiling, mix the softened butter, garlic powder, and chopped parsley in a small bowl until smooth.
Coat and Serve: Remove the hot corn from the water, drain well, and immediately brush the garlic butter paste over the hot cobs. Season with a pinch of sea salt and serve warm.
