This recipie serves two for a reason.
Place ice cream in a wide, shallow (preferably white china) bowl.
Drizzle liquor over ice cream scoops.
Garnish with mint.
Next time you're out with a special someone (or ones) at a restraunt you excpect has decent ice cream, they'll usually do a particularly nice job presentation-wise if you ask for this. ("B&B over your malted vanilla ice cream," if you're at Seattle Catch Bistro.)
