Hmm, thanks Lucy. I'm wondering about the 'safety' of the pressure cooker, but I am of the opinion that it should be 'safe' if it isn't too full and the valve is clean. Would that be correct?

I think my Mum has (or had at least) a pressure cooker, one of those thick aluminium ones, but I'm not sure how often she used it. She's very old school, simple cookery (European), so I guess I should ask her too.

I know what you mean about aspiring to be like your Granny. I'm like that about my Great Aunt. One of those fabulously brilliant, clever and strong women.
