That soft serve is what DW refers to as custard (not to be confused with lovely custard that you put on apple crumble!) in south NJ, and I went to a "custard stand" in NJ and that's what it was.
I think calling it that must be a regional (NJ?) thing, because I would call it soft-serve. All the same, I understood what you were on about when you first posted it & figured that the 'custard' bit must be something US-regional.

I have gotten nice soft-serve ice cream at ice cream stands here before - just steer clearing of Mr Whippy & others like that. Although sometimes you don't know what you're going to get until you've already bought it.
Even in the US, over the time I grew up & lived there, the quality of soft-serve at various places changed over time, I think. Like I can't stand McDonalds ice cream (their milkshakes are the worst!

), and even DQ seemed to be going that way. I don't know what it is really. I just remember that when I was a kid, the soft-serve ice cream you got seemed to taste more like real ice cream. And more places than not, nowadays, seem to serve something that tastes more artificial.

That's why I like to make my own ice cream - I know what's going in it. Sugar, milk, cream, egg, flavouring like fresh strawberries or real chocolate/cocoa or vanilla. Simple and delicious! And it's soft-serve when just freshly made.
