Orange Peel Drink

1. Thoroughly wash the oranges before peeling them. Peel the oranges, trying not to take the white part as it can make the drink bitter. 
2. Put the orange peels in a pot, add water, and bring to a boil. Simmer for 15-20 minutes. 
3. Turn off the heat and add sugar, stirring well until it is fully dissolved. 
4. If you're using vanilla extract, add it at this point and stir well again. 
5. Let the drink cool down, then strain it to remove the orange peels. 
6. Serve the drink cold, adding ice if desired.

Enjoy!
