and the winner is...

Lime sherbet. I've had 3 mugs so far today. The other ice creams were ok (I tried Butterfinger and Peanut Butter Tracks, too, last night) but the sherbet is far in the lead.

What Donavon neglected to mention is that, at first, the only sherbet I could find was an $8 party tub. Not only was I concerned that I wouldn't be able to eat a party tub (I'm less concerned and a little regretful now) but also I didn't think it would fit in our freezer. I was kind of close to crying at that point. After careful searching, there was some sherbet disguised in ice cream packaging. I had NO idea that sherbet came in any packaging other than those clear tubs with a thick white lid that you satisfyingly peel off, like on Fluff tubs. Unfortunately, they didn't have rainbow sherbet in the more reasonable size, which caused a little distress. Eventually I pulled it together and settled on Key Lime, with the other ice creams as back up in case the flavor was all wrong.
