How to make:
STIR bourbon and maple syrup in base of mixing glass until syrup dissolves. Add bitters and ice and STIR again. Strain into ice-filled glass.
*To make fat-washed bourbon: Grill 4 slices of bacon to obtain 30ml/1oz of warm fat (originally made using Benton's bacon, hence the name, but any extra-smoky bacon will suffice) and pour this into a 70cl of bourbon (in a 75cl bottle). Leave to infuse at room temperature for a day before placing bottle in a freezer to solidify the fat. Then clarify the bourbon by straining into a clean bottle.
If you like bacon and Old-Fashioneds then you'll love the Benton's Old-Fashioned.
