Icecream was solved in 1950s in USSR.
I've had lots of different ice creams. I enjoy the differences. Turkish Ice Cream is chewy for example. I like soft serve sometimes too and the quality varies widely from icy (meh) to smooth (yum) to light and creamy (yum). There's a branch in Japan that advertizes it's 25% whipped cream. it's great! What's 1950s USSR ice cream like?
Turkish I would not consider an icecream at all (and I lived in IST for half a year).
it is hard to convey in words the sheer delight. has to be experienced.
