OK, so here's the deal: I was (accidentally) browsing this ice cream site (Breyers, to be exact) when I came across the FAQ section. There was a question about whether the natural flavors in the ice cream contained alcohol, and the answer was that yes, most natural flavors do contain alcohol as a critical component, something something. The flavor usage rate is typically 0.2-0.4%. I don't know too much about food science to know what that means, but I understand it means that there is some alcohol in the ice cream.
The question is, does alcohol in such a minute quantity count as haram? Second, if one does have food which contains such, what should one do with it? I know I wouldn't buy it again but what to do with the ice cream in the freezer? I dunno, I'd feel really bad about throwing a bunch of half-used cartons in the trash can... But nor can I hand them over to anyone else, can I, considering how they're open.
For reference, here are the exact words from Breyers:
Do your "natural flavors" contain alcohol?
Almost all "natural flavors" such as those used in Breyers has alcohol as a critical component of the liquid which contains the flavor compounds. However, keep in mind the flavor usage rate is typically 0.2-0.4%. This would mean an entire 56 oz. package would contain very little alcohol and a single scoop would contain even less.
