The Bruce Wayne
Something magical happens to iced coffee when you shake it with whiskey and maple syrup: You get a lovely, creamy head of foam on top — almost like a Guinness — that disguises the dark depths below (which contain enough caffeine to power any nocturnal superhero).
- 75ml Grubbs Concentrate
- 50 ml water
- 60ml bourbon
- 8 to 15ml maple syrup (depending how sweet you like it)
Measure all ingredients into a cocktail shaker filled with ice and shake thoroughly, until chilled and foamy. Strain into glass over ice.
