Place water and the rest of the syrup ingredients in a small pot, bring them to a boil on a high heat, lower the heat and let simmer for about 5 minutes, stirring occasionally, until you get a "syrup" consistency.

Make an espresso and heat milk.

Foam milk in a jar or with a hand blender.

Pour milk in a tall glass or mug. Spot it with a few tablespoons of espresso.

Add 1-2 tablespoons of the syrup, depending on how sweet you want your Latte.

Mix and enjoy!
