Fair warning, do not get the Baskin Robbins "Daiquiri Ice". It may look just like the "Margarita Ice" you had the week before (which really should have been called "Limeade" -- very refreshing on a hot day), but there's a subtle difference. It's called "rum flavoring" and it's carefully calculated to assault every tastebud with nastiness.
It took a really long time to melt and run down the sink too. Okay, so even culinary masochists have their limits.:)
