Well - in our forced time together my kid and I have been talking a lot about ice cream and perhaps consuming too much of it. But the question my kid had was "What's a half gallon?" We're thinking of making a special trip to get something special at Fenton's in Oakland, and they still have half gallons. This used to be the standard although there are a few that still have half gallons (Tillamook and some regional dairies come to mind) . However, the big brands have nearly all gone to 1.5 quarts, which is 75% of a half gallon. I remember when 1.75 quarts was the first step.
The other thing was that we found Haagen-Daz on sale. But then I looked at the label and it said "14 oz." I mean - for the price we're paying why not a full pint?
