Rinse fresh peppermint leaves thoroughly under cool water. If using dried peppermint, skip this step.
Bring water to just below boiling point (around 200°F/93°C). Boiling water can make the tea taste bitter.
Place fresh peppermint leaves in a tea infuser or strainer. If using loose dried peppermint, use about 1 tablespoon per 2 cups of water.
Pour the hot water over the peppermint leaves.
Steep for 5-7 minutes, depending on desired strength. Fresh leaves might need an extra minute or two.
Remove the infuser or strain the tea.
Add honey or your preferred sweetener if desired.
