Elaine asked about the rapini. It is different from rape seed also called canola. Both have loads of tiny yellow flowers.

This is some store bought rapini, that is quietly getting wilted and will become tonight's supper. It has a strong somewhat bitter, somewhat mustardy taste that I am quite fond of. I usually saute it lightly in olive oil and lots of garlic. Finish with a generous squeeze of lemon and some salt. And it goes well with japanese eggplant and home grown garlic.
I was keen to grow some this summer, and did not realise that the stems need to be pinched off. Mine has gone to bloom and now seed, so it looks like I have to replant the crop.
