Just thought I'd share this, in case anyone's interested.
I was down in Ikea the other day picking up some storage jars, and well...a trip to Ikea to buy just one thing is never possible... when I came across this chopping board. I found it pretty annoying when using a normal sized board and preparing a large amount of vegetables etc and having to sweep them onto the worktop or onto a plate or whatever. SOooo I bought it and can confirm it does the biz. Roughly 18" x 21" (or 46cm x 53cm) and coming in at a massive ?7.99, you can't really go wrong

Don't forget to pick up some Mineral Oil at the same time (sold in the Kitchenware Dept) because your board will need to be seasoned before you use it
