It’s been a couple months since my last soup post, so this one is long overdue. Soups are a vital part of my diet; they are versatile, easy to prepare, and a seamless way to integrate more homemade broth into my eating routine. Today’s lettuce soup is a nice change of pace, and a unique way to avoid the incessant crunching and chewing that comes from eating a plateful of lettuce.
There are two main cuisines with a history of enjoying lettuce in their soup. In Chinese cuisine, it is added as a finishing vegetable, much in the same way you’d add herbs like cilantro or scallions; for example, our local Vietnamese restaurant serves its Chinese-inspired Hu Tieu soup with lettuce on top. Today’s recipe favors the French preparation of lettuce soup, which is often blended (or run through a sieve) and flavored with cream.
Any lettuce will do for this recipe, with the exception of iceberg, because it probably won’t add much flavor. This dish is served both cold and hot, and we prefered the hot version. Lettuce soup has a flavor that’s hard to describe – earthy but not dirty, sharp but not biting. I’ve found that cooking down a leek in the chicken broth enriches and balances the soup; adding a few sprigs of parsley and some lemon zest help brighten its top notes as well.
