I’ve in the same situation and have been trying to deplete my stocks too. The following won’t necessarily help you clear out that half bottle of Midori or Amarula but are quite simple, tasty and also aren’t just a G&T which is always the simplest and often best option:
Bourbon Sidecar - this apparently serves 2 - I have my doubts…
4 oz (120 ml) bourbon
2 oz (60 ml) Cointreau
1 1/2 oz (45 ml) fresh lemon juice
2 dashes lemon bitters (I never bother with this to be honest)
twists of lemon as garnish
Shake the Bourbon, Cointreau, lemon juice and bitters with ice cubes until a thin layer of frost appears on the outside of the shaker. Pour into cocktail glasses. Garnish each glass with a twist of lemon and serve immediately.
Dark & Stormy
Since living in Brixton this has been a bit of a go-to. The corner shops tend to have a better variety of rums than any other spirits. This works fine with any golden - or dark rum. Often this will be a half bottle of Cockspur Fine from Top Joe’s on Brixton Hill.
Ingredients: Rum (a solid slug), coke to top up (edit - yes, got this wrong - ginger beer!). Big lime wedge - squeezed and then dropped in. Ice. Combine all in a decent sized glass. You need the lime to make it classy
Finally, the Hawksmoor classic - Shaky Pete’s Ginger Brew:
Shaky Pete’s ginger brew
This turbo shandy is Hawksmoor’s most popular cocktail.
50ml lemon juice
35ml gin (we use Beefeater)
50ml ginger syrup (whizz peeled ginger in a blender with a basic sugar syrup)
Ale, to top (we use Fuller’s London Pride)
In a heavy-duty blender (a NutriBullet would be ideal), blitz the lemon, gin and syrup with five ice cubes. Pour into a beer glass and top with ale.
