Prepare the tea. In a small sauce pot over high heat, add the water, ginger, cinnamon, star anise, and 6 cloves. Cook for 10 minutes, strain, and let it cool down.
Make the pistachio mix. First, peel the pistachios if they came in shell.In a blender, add ½ cup of the tea and the pistachios. Blend for 1 minute or until you make a smooth paste.
Add the other ½ cup of tea, the coconut milk, coconut cream, evaporated milk, condensed milk, vanilla, and cinnamon. Mix on high for 1 minute.
Add rum if desired, and mix it in for 1 minute.
Bottle the coquito in a glass bottle or serve immediately over ice and garnish. Buen provecho.
Notes
Pistachio. If you want to use peeled pistachios, you'll need 1 ½ cups.
Drink Texture. You'll have small pieces of the pistachios that'll give the drink a small crunch. If you don't like this, strain the pistachio water before adding the rest of the ingredients.
You can choose to add rum or not. I like to make it without so it can be a kid-friendly version and add it to each drink. If adding rum, use 1 ounce of rum per drink.
Yield. Each drink is a little over 8 ounces, without the ounce of rum.
