Working from their kitchen-studio in Lambertville, N.J., Christopher Hirsheimer and Melissa Hamilton have been quietly innovating food publishing. The media-savvy pair--Hirsheimer was a founder of Saveur magazine and Hamilton worked for Cook's Illustrated--create and publish Canal House Cooking, a thrice-yearly magazine-book hybrid replete with lush food photos and home-tested recipes. This refreshing chilled soup (from their latest edition) combines rich avocados with crisp cucumbers. It's an ideal dinner for a hot summer night, as it requires no cooking and can be prepped in just a few minutes.
