Cold Lettuce and Zucchini Soup with New Onions and Fresh Herbs

On a late-june evening, I entered a courtyard in the Fifth Arrondissement, right near the picturesque Rue Mouffetard, one of my favorite streets in Paris when I was a student there so many years ago. Beyond the courtyard, I found myself in a large garden in front of an apartment building. After climbing two flights of stairs, I arrived at the home of Irving Petlin, an American artist, and his beautiful wife, Sarah. The two expats have lived here on and off since 1959. Sarah frequents the local markets, going to the Place Monge for her onions and garlic, making sure she visits her potato man from North Africa. Having chosen peonies for the table, she arranged them in a vase next to a big bowl of ripe cherries, making her table, with the Panthéon in the background, as beautiful as a perfectly orchestrated still life. At the meal, I especially liked the soup, which calls for lettuce leaves—a good way, I thought, of using up the tougher outer leaves that most of us discard, but which still have a lot of flavor. The French have a long tradition of herb- and- salad soup, something Americans should be increasingly interested in, given all the new wonderful greens we’re growing in our backyards and finding at farmers’ markets. I often replace the zucchini with eggplant and substitute other herbs that are available in my summer garden. This soup is also delicious served warm in the winter.
