Prep the ginger. Rinse and thinly slice the ginger.
No need to peel if it’s clean and fresh.
Bring water to a simmer. Add 2 cups of water to a small pot and bring to a gentle simmer, not a rolling boil.
Simmer the ginger. Add the sliced ginger. Simmer for 5–8 minutes, depending on how strong you like it. Longer simmer = more heat.
Add the peppermint off heat. Turn off the heat.
Add dried peppermint (or a tea bag, or fresh leaves). Cover and steep for 3–5 minutes. This keeps the flavor bright.
Strain and taste. Strain the tea into a mug.
Add honey and lemon juice to taste. Stir well.
Serve. Garnish with a lemon slice if you like. Sip warm, or let it cool and pour over ice for a refreshing iced version.
