Prep the Zest & Ginger: Remove the lemon and orange zest, avoiding the white pith. Peel and chop the fresh ginger root.
Blend the Base: Add the zests and ginger to a blender with a splash of water. Blend until smooth, adding water as needed for a thick but pourable consistency.
Add Seasonings: Transfer the mixture to a bowl and stir in the black pepper, turmeric, and cayenne pepper. Adjust seasonings to taste.
Form the Cubes: Spoon the mixture into an ice cube tray. Freeze for several hours or overnight until solid.
Serve: Pop a cube into a mug, pour in 8-10 ounces (240-300 ml) of hot water, stir, and sweeten to taste with honey or maple syrup.
Store: Transfer frozen cubes to a freezer-safe bag or container for easy single-serving use.
