• For the most authentic flavors, use pure toasted (Asian) sesame oil for the marinade and medium-grain glutinous rice (like that used in Japanese cooking) for the ssam. These ingredients, as well as soybean paste (similar to miso but more strongly flavored), are available online at www.kgrocer.com. For the ssam, we suggest using the long, green chile peppers found at most Asian markets (jalapeños can be substituted in a pinch).
