Heat 1 cup of water in a medium saucepan over medium heat.
Remove from heat and add the honey. Stir until the honey dissolves. Pour into a large pitcher and stir in remaining 2 cups of cold water and lemon juice.
Chill and serve over ice with orange wedges or a lemon slice.
For low carb, keto, and vegan version: Skip the honey simple syrup. Just combine 3 cups water with 1 cup fresh lemon juice and add liquid stevia to taste.
