I'm throwing a friend of mine a blast from the past birthday party complete with laser tag (we're 80s babies) and an ice cream bar. I'm planning on buying good vanilla ice cream and laying out a bunch of toppings--but with a semi-adult twist. Aside from the usual suspects like hot fudge, crushed cookies and candy, what would you have on hand? I love mandarin oranges in syrup or lychees in syrup over mine, maybe azuki or sweet mung beans. Other ideas?
