I have a rather weird yearning for raw meat from time to time. I like to nibble the 'extra lean mince' we get from Tesco's. Steak tartare sounds lovely, BUT my bossy doc sister told me to stop eating raw meat At Once. Apparently one can get all sorts of really nasty things from uncooked meat. She usually knows her stuff, so I don't nibble any more.
Joe, I'll try your pineapple tip for sweetening rhubarb.
