We have decided this is an excellent cocktail for the winter months.
I made a pitcher of the GMT for the podcast, but you can follow the same ratio to make a single cocktail.
1 Part Gin
1 Part Blood Orange Cordial (Blood Orange Juice and simple syrup would work as well)
2 Parts Pink Grapefruit Juice
1 Dash Bitters
Top with ginger ale or soda
Garnish with orange slice.
