Step 1: Prepare the Ingredients
Peel and slice the onion, lightly crush the garlic cloves, and wash and slice the fresh ginger.
Step 2: Bring the Water to a Boil
Pour 4 cups of water into a medium saucepan and bring it to a gentle boil over medium-high heat.
Step 3: Add the Ingredients
Add the cinnamon sticks, garlic, ginger, and sliced onion to the boiling water.
Step 4: Simmer
Reduce the heat to low and let everything simmer gently for 15 minutes. This allows the flavors to infuse into the water.
Step 5: Strain
Remove the saucepan from the heat and strain the liquid through a fine-mesh sieve into a teapot or heatproof pitcher.
Step 6: Add Optional Flavorings
If desired, stir in honey and fresh lemon juice after the drink has cooled slightly. This helps preserve the flavor of the honey.
Step 7: Serve
Pour into mugs and enjoy warm. Leftovers can be refrigerated for up to 2 days and reheated before serving.
