1 measure blue curacao
1 measure Bailey’s Irish Cream
top up with one pint cider (or lager if you prefer)
The end result is a sort of greenish-brown liquid with scummy bits floating in it and a THICK layer of scum on top. Tastes wonderful, especially if you dunk chocolate bars in. (These are referred to as Control Rods, and the bar of preference is a Toffee Crisp, if only because the crisped rice pieces start floating around in the drink and making it look even nastier)
NOTE:
The nuclear wastes I’ve seen mix blue curacao and orange juice (and vodka). Turns everything a very nice shade of fluorescent green.
