Pull the silk from the ears as you shuck. Pinch off and discard any brown, dry tips; you want only the pale yellow-green strands. Rinse the silk well in a sieve under cool running water.
Bring the water to a boil in a medium pot, then add the silk. Reduce to a gentle simmer and cook uncovered for 10 minutes. The water will turn a pale golden colour.
Turn off the heat, cover the pot, and let steep for another 5–10 minutes. The longer it sits, the richer and sweeter the flavour.
Pour through a fine-mesh sieve and discard the silk. Serve warm with a squeeze of lemon, or chill completely and pour over ice with fresh mint. Add a touch of honey or maple syrup if you like it sweeter.
Keep leftover tea in a sealed glass jar in the fridge for up to 3 days.
