There was no way I was going to leave Bill Maxwell’s farmstand in the Union Square Greenmarket yesterday without some of these beauties.  Garlic scapes are the curling stalks, or ‘scapes’ of conventional garlic when it first appears in the spring.   They are removed by the farmer in order to encourage the growth of the bulb below.  They have a mild, fresh aromatic taste and hardly need any cooking.  I use them in any way I can;  tonight they will grace a simple dish of pasta.
