I just mixed up this variant on the sidecar:
1.5 oz Metaxa brandy
.75 oz Cointreau
.75 oz Lime juice
.75 oz Lavender simple syrup
.75 oz Domaine De Canton
I made the simple in a 1:1 ratio. 1 cup sugar, 1 cup water, and 1 tbps dried lavender.
I got the idea from a bar in Seattle however they use lemon juice instead of lime which is good too. My wife had this there and she was crazy about it.
