In a medium saucepan, put annatto in water and bring to a boil over high heat. Reduce to medium heat and boil for 3 minutes to get color from annatto. Add the remainder of the ingredients, stirring with a whisk to dissolve cocoa powder. Return to a boil and cook for 3-5 more minutes until the cocoa powder and chocolate are fully dissolved. Strain out solids through a fine sieve and discard. Beat liquid into a foam with a whisk or blender. Makes 1 serving.
