I knocked up some coq au vin with mustard mashed potatoes for dinner last night, and as the pile of potato peelings and onion skins etc. grew, and as I pushed it into the bin, I remembered that Dave Wooding used to feed the family's kitchen waste into a wormery that converted it into compost and plant feed.
I've dug up some details of a baby one on the internet this morning. It is too late to get it for this weekend, but I'll order one in time for the first weekend in Feb as it will be fun - and educashional - to set it up with the New Ninja Bomber. Unless I miss my guess just the name of the red tiger worms that power it will be enough to pique a six year old boy's interest.
