Nightcap.

I rarely go out for hot cho-co-late as mine is hard to beat. It is also very rich, so not to be abused. 
Instead of the usual Latin American inspired aromatics, tried a more Mediterranean combination of citrus peel and lavender: a keeper.

For two:
- 1/4 c. Dark cocoa powder
- 1 T butter
- 2 c. whole milk
- 1/4 c. cream
- pinch of sea salt
- stevia / other sweetener to taste (I used approx 10-15 drops)
- 2 T shredded citrus peel (lemon + orange)
- 10- 15 drops lavender essence

Melt butter in heavy-bottomed pan.  Add cocoa and salt, stirring until smooth.  Add cream.  Mix to break down any lumps.  Add milk, sweetener, shredded citrus peel and lavender essence.  Heat until nearly boiling, let simmer for a minute or two.  Beat until frothy.  Garnish with citrus peel, or even lavender flowers, if you'd like.
