Perpetual stew feels like a gimmick but stew does taste better on day 2 and 3 for sure.

I agree that the perpetual part is kind of gimmicky, but having a stew for a week or two and stretching it out with additional ingredients can be a big time saver and, as you said, in some ways it gets better with time as it's cooked more.

Slightly different, but many of the best ramen broths are the kind that keep going for ages, so there's definitely more to it than just a gimmick.
