What’s so special about local farmer’s markets?  See for yourself in this hands-on class lunchtime visit to the farmer’s market, where you will discuss the benefits of buying locally grown produce, ways to get the most for your money, and some shopping rules of thumb.  Then, depending on what’s available at the market that day, you’ll return to the BCAE with fruits and vegetables to taste, and learn to cook some dishes with a bounty of farm-fresh ingredients.  Meet at 11 at the Boston Center for Adult Education, 122 Arlington Street.  The instructor is Leah Bloom, and the cost is $45 plus $18 for materials.  BCAE members enjoy a discount on the class cost, paying $39 plus the materials fee.  To register, and for more information, log on to www.bcae.org.
