Once in winter a soccer player posted on Instagram that it was never too cold for ice cream. The day after the club tweeted that the player would miss the match that day due to illness...
I prefer my ice cream in the summer. I currently live in a high desert, so cold things during the summer really helps. Plus, to me the ice cream tastes much better when it's hot and not cold. Though, there has been a few times I did eat ice cream in the winter. >.>
Definitely all year round. There is this fantastic ice cream place, close to me, that makes amazing ice cream from fresh seasonal fruits. So the flavours they offer change all the time. You know it's fresh when you see the tiny seeds of the strawberries or small pieces of green apple skin in your cream.
