Karaage is typically marinaded with mirin, soy sauce, sake, minced garlic, and ginger for a complex and flavorful kick, but what makes the dish stand out is that the meat is coated in potato starch. Potato starch absorbs liquid better than flour, which crisps up the meat's exterior, and it also has a higher percentage of amylose, which, when linked with amylopectin, gives that satisfying crunch.
