Perfect cup of hot cocoa

1 heaping Tbs. unsweetened dutch-process cocoa powder
1 Tbs. sugar
a teeny pinch of salt
2 Tbs. water
1 c. milk (anything from 1% to whole will do)
1/4 tsp. vanilla extract
a little shake of Ceylon cinnamon

Whisk together the cocoa, sugar, salt, and water. Bring to a gentle boil and boil for a minute, then add milk, vanilla, and cinnamon. Stir. Bring almost, but not quite, to the boiling point. Pour into a mug and enjoy.

Serves one; can be multiplied to serve many.
