We had one of these when I was a kid. We used it every summer, at a cottage we stayed at in the Adirondacks that had the smallest and most rustic of kitchens. Our 70's board didn't look like this of course. It was an ugly plastic thing.
So when Ivy and Christy recommended the over-the-sink-board idea to Maya to help her extend her kitchen counter space, I was flooded with nostalgia for the summer meals I helped my mother cook in that small kitchen. I went in search of the C&B model Christy mentioned, to see what they look like these days.
C&B's update (pictured) is definitely an improvement on looks, and we like the built-in colander. And at $29 it's less expensive than this similar model from Williams-Sonoma and this one from Kitchen Emporium. But we actually prefer this $17.95 polyprolylene one because it's dishwasher-safe and easier to keep sanitary.
Maybe we'll try to dig up the original.
