For the warmer months, Chris Parsons is putting away the meat cleaver, mallet, and cast iron skillet and picking up tweezers, small size melon-baller, and mandolin in the kitchens of Catch at The Terrace on Martha's Vineyard and Catch in Winchester, Massachusetts, where his down-sized ingredients of Baby Bananas, Baby Chioggia Beets, and Japanese Brown Beech Mushrooms to Kumquats, Champagne Grapes, and Quail Eggs are the next BIG trend but customary at Catch at the Terrace and Catch. Ingredients show up in baby, petite, dwarf, and miniature varieties. Swedish Peanut Fingerling Potatoes, tiny Heirloom Chickpeas, Petite Gnocchi and Lobster Agnolotti add color, flavor, and texture to Mediterranean-inspired plates without weighing the diner down. To keep that small thought going, Potato Pearls (shaped with a mini-melon-baller) give that added dainty, delicate, and light appeal to a dish.   Seafood-on-the-small-side, like Taylor Bay Scallops, Sweet Maine Shrimp, and Rouget (red mullet) may be tidbit size, but they produce delicious taste explosions on the tongue. The satisfying crunch of tiny Breakfast Radishes and fragrance of leaves hand-picked from herbs and Celery Hearts tossed in a salad and presented in a tight package on the plate is a “little” indication that just because something is small doesn’t mean it’s not big on flavor.
