Heat the milk in a small saucepan over medium heat until it starts to gently simmer.
Whisk in the turmeric, black pepper, cinnamon, and ginger until well combined.
Reduce heat to low and let simmer for 3-5 minutes, whisking occasionally.
Remove from heat and stir in honey or maple syrup to taste, if using.
Strain through a fine-mesh sieve if desired for a smoother texture.
Serve warm in mugs and enjoy immediately.
