Add sugar cube to mixing glass and add the drops of angostura on top of it. Add some of your whisky and stir until sugar dilutes. Add the rest of your whisky with ice and give it a nice stir. Pour over fresh ice in a nice old-fashioned glass.
Dark Cherry, Orange zest
Do a twist on your Old Fashion cocktail by replacing sugar cube with a spoon of marmalade of your choice & adding a different type of bitters. Ex: 1 spoon apricot marmalade & 2 dash orange bitters.
