Whatever we drink with this movie has to have moonshine in it, right?
TOM, DICK, AND HARRY
1½ oz Moonshine*
2 oz Fresh grapefruit juice
½ oz Fresh lime juice
3½ oz Ginger beer
Shake first 3 ingredients with ice, strain, pour, add ginger beer and grapefruit twist.
*Since the prisoners in Stalag Luft III make their moonshine from potatoes, you can also use vodka and be "movie appropriate." Change amounts to 2 oz vodka, 1 oz grapefruit juice - rest is the same (it becomes like a Moscow Mule with more acid kick!)
