Ben & Jerry's has released a new flavor called, "Mission to Marzipan". It's a sweet cream ice cream with almond cookies and a marzipan swirl. Erin picked this up when I was in Las Vegas and found it to be weird tasting and basically inedible. I agree that it isn't the best B&J's flavor out there, but didn't have much problem eating the stuff.
We actually had to research marzipan to figure out what it was. Strangely, after reading about it, we're still not sure what it is. Here's the best description we could find:
"Marzipan is a confection consisting primarily of sugar and almond meal. It derives its characteristic flavor from bitter almonds, which constitute 4% to 6% of the total almond content by weight. Some marzipan is also flavored with rosewater."
Mission to Marzipan hits your tongue with a strongly flavored almond extract bite that rings a little weird. Maybe this is how marzipan always tastes. Who knows? At any rate, I'd say this flavor is for marzipan fans only, assuming marzipan fans exist.
