While stir-fries have long gone hand-in-hand with rice, this recipe shows the versatility of the dish. Here, a quick stir-fry is transformed into a flavorful, unconventional pasta sauce. Five spice is a Chinese seasoning that is said to incorporate all five tastes: sweet, sour, bitter, salty and umami. In this recipe, its blend of star anise, cloves, Chinese cinnamon, Sichuan peppercorns and fennel intensifies the robust flavor of the mushrooms. Don’t overcook the broccolini; it should be crisp, with a bright green vibrancy. You could easily substitute broccoli, green beans, snow peas or other crunchy greens. And don’t skip the butter (or use vegan butter, if you prefer), as it provides a beautiful richness which brings the sauce and ingredients together.
