Coffee jelly

Coffee jelly (コーヒーゼリー, kōhī zerī) is a jelly dessert flavored with coffee and sugar. Although once common in British and American cookbooks, it is now most common in Japan, where it can be found in most restaurants, cafés, and convenience stores. Coffee jelly can be made using an instant mix or from scratch. Coffee jelly is also frequently used in bubble tea/coffees.
