Certain dishes were made for springtime. Today's episode of EVERYDAY FOOD showcases three meals that celebrate the flavors of the season. First, Lucinda makes roasted salmon with herbed yogurt, accompanied by lemony smashed potatoes. John prepares garlic-roasted leg of lamb and serves it with a side of Israeli couscous with parsley and shallots. Today's "Have You Tried?" ingredient is watercress. Anna shows how to shop for and store this delicious peppery green, which is perfect for a simple salad with manchego and orange. Finally, Sarah uses a spring classic - asparagus - in a beautiful asparagus, leek and gruyere quiche.
