Dozy DH unplugged the freezer around 7pm last night and I didn't realise until 9am today. Plugged it back in straight away after shutting the door really quickly, and the temperature read -3.
Dozy me doesn't know whether that means everything is ok, still frozen, and safe to eat (we're vegetarian so nothing truly food poison-worthy, I don't think). I'm assuming because it didn't go above 0 degrees it's still technically frozen? Duh
