Never come across these before. DH picked them up in Lidl and we'll be trying them out shortly. The cooking instructions say to drop them into boiling water and cook for about 3 minutes. Has anyone else had these?
I googled them and found that they are a cross between kale and Brussels sprouts. Fifteen years in the making, apparently! And according to an article about them in The Telegraph earlier this year, they have been on sale in M&S, Asda, Sainsbury, Waitrose and Co-op. Well I've never seen them in Sainsbury, M&S or Co-op and I shop in those stores regularly. Probably don't live in a posh enough area
