In a mixing glass add the maple syrup and bourbon and stir well until the maple syrup properly dissolves. Add the bitters and stir again before straining into a rocks filled lowball glass.The original recipe for this calls for bacon fat washed bourbon, which can be made by grilling 4 slices of bacon and adding the fat (around 30ml) to a 70cl bottle of bourbon and leaving to infuse for a day. After the day place the bourbon into a freezer to solidify the fat, before clarifying the bourbon by pouring into a new bottle.
