How to do it:
Fit an undermount sink with a cutting board for more prep space. Measure the length and width of the basin, adding ½
inch to each side. Trim a piece of butcher block to size with a jigsaw. Then create a lip around its underside so that it will rest on the edge of the counter. Estimated cost:
18-by-12-inch maple block, about 86; Butcher Block Co.
