The third installment of our Sous Chef Series visits Asia by way of Los Angeles, where Sara Johannes runs the kitchen at WP24, Wolfgang Puck's glamorous modern-Chinese restaurant at the Ritz-Carlton Los Angeles. There, her spice-rich baby back ribs--which are seasoned with a combo of classic Chinese flavors (ginger, garlic and soy sauce) and the sweet, saucy appeal of American barbecue--are a menu staple. Her hoisin-spiked sauce has the makings of an essential; keep this one on hand for grilling season.
