Hannah's Korean Salmon

Hannah's family is from South Korea, and she will be making a Korean salmon marinade, which is a popular recipe used there. She starts by adding garlic puree, Korean chilli paste, soy sauce, honey, toasted sesame oil and her special ingredient, sesame seeds, into a jug and mixing them all up. Next, Hannah puts pieces of her salmon onto individual baking sheets and spoons the marinade on. She garnishes them with freshly chopped spring onions, and then her salmon is ready to be cooked in the oven. Hannah wears a colourful Korean outfit and treats her friends to some local Korean kimchi, but will her pals be able to guess her special ingredient?
