Cocktail du Jour: Ginger Margarita

I purchased this bottle of ginger liqueur, Domaine de Canton, after admiring its unique orientalist bottle.  I'm sure my husband loves my habit of buying fancy bottles of stuff I've never tasted (the Campari experiment being my worst decision) and taking up precious Bourbon real estate on the bar.  

Not knowing exactly what to make with such an unusual elixir, I searched for ginger-inspired cocktails.  That is how the ginger margarita was born.
