Funnily enough Ive just dug mine out and have made bitter orange ice cream today ready for Easter family dinner to go with a pistachio tart. Mine is a ken wood. I have made a few errors that I thought I would share!
It DOES need a 24 hour freeze beforehand (the bowl). I thought, nah, 6 hours will do. It didn't and I ended up with peanut butter custard, watching it go round and round sadly doing nothing.
You need space in your freezer for the bowl at all times really if you disorganised like me. If I want to make ice cream I want to make it NOW! I'm rarely ahead enough of the game to remember to put it in the freezer the day before. As such, it needs cupboard space too, if you aren't going to keep it there.
Other poster is quite right. Storing the ice cream in the bowl is a mistake. Even covered with cling film, lids etc, the ice cream goes a bit dried up round the edges and unappealing.
What to do with the egg whites? I've now got 6 on the fridge.
Nigel Slater has a nice chapter in Real Food about ice cream and he probably has recipes floating round on the net.
Only once did I scramble the custard and it happened in the blink if an eye.
Good luck on your ice cream adventures. They are super tasty and I wouldn't be without mine, even of I only use it rarely I know it's there nestled in a love nest with my waffle maker, blow torch and juicer
