This rustic soup features green garlic, a delicious seasonal specialty that comes to the market in early spring. The tender shoots are as small as scallions or tiny leeks. Left in the ground, they will grow to be full-sized heads of garlic by mid-summer, but these young specimens are wonderful, with a mild but distinct garlic flavor. If you can’t find them, wild ramps make a good substitute. Otherwise, make this soup with 6 to 8 sliced cloves of regular garlic. The raw tomatillo salsa adds a welcome note of acidity and crunch. You can make it as spicy as you like by varying the amount of jalapeño.
02Add 10 cups water and 1 tablespoon kosher salt. Bring to a boil. Reduce heat to a simmer and cook until chicken is tender, but not falling off the bone, about 1 hour. Turn off heat and skim fat from surface of broth. (May be prepared up to this point several hours ahead, or up to a day in advance, and refrigerated.)
03While chicken is cooking, prepare the green garlic shoots: peel tough outer layers and roots, then rinse well. Split shoots lengthwise and chop both white and tender green parts. Set aside.
04Make the tomatillo salsa: drain diced white onion and transfer to a small bowl. Add tomatillo, jalapeño, lime juice and a little salt and stir together.
05Just before serving, reheat soup, add chopped green garlic to pot and simmer 5 minutes. To serve, put one chicken leg in each bowl (alternatively, remove meat from bone and shred) and ladle soup over it. Pass tomatillo salsa and lime wedges at the table.
