Heat the water: Bring water to a boil, then let it sit for 30–60 seconds. You want it hot, not scalding.
Prep the lemon: Roll the lemon on the counter to loosen the juices, then cut and squeeze.
Strain out seeds if needed.
Flavor the cup: If using ginger, add the slices to your mug first and pour the hot water over them. Let steep 2–3 minutes.
Add lemon juice: Stir in the fresh lemon juice. Start with 1 tablespoon; you can add more later.
Sweeten with honey: Stir in 1 to 2 teaspoons honey until fully dissolved.
Taste and adjust.
Finish and serve: Add a lemon slice or mint if you like. Sip warm and enjoy.
