What is Anmitsu?
Anmitsu is a dessert made of small cubes of agar jelly, a white translucent jelly made from red algae. The agar is dissolved with water (or fruit juice such as apple juice) to make the jelly. It is served in a bowl with sweet azuki bean paste or anko (the an part of anmitsu ), boiled peas, often gyūhi and a variety of fruits such as peach slices, tangerine, pieces of pineapples, and cherries. The anmitsu usually comes with a small pot of sweet black syrup, or mitsu (the mitsu part of anmitsu ), which one pours onto the jelly before eating. Anmitsu is usually eaten with a spoon and fork.
