Breaking avocado news: if you put them in the fridge, they go all weird.
I expected them to just last longer and maybe go a bit more mushy (that's what happens when I store half one in a container in there), but in a loose bag they went partly hard – I thought at first they were frozen on the bottom or something, but it's actually like just one side of them is dried out. Really odd.

(Think I'll store them whole in an airtight container next time and see what happens.)
