Matcha ice cream and Monaka

Green tea ice cream (抹茶アイスクリーム Matcha aisu kurīmu^?) or Matcha ice (抹茶のアイスクリーム Matcha no aisu kurīmu) is a Japanese ice cream flavour. This flavour is extremely popular in Japan and South Korea, and other parts of East Asia, and almost all ice cream manufacturers produce a version of it, including foreign vendors such as Häagen-Dazs, Baskin-Robbins, and Natuur.

The name matcha comes from a specific type of green tea used in the Japanese tea ceremony.

Green tea ice cream is also sold in monaka form.

It has been available in the United States since the late 1970s, primarily in Japanese restaurants and markets, but is currently moving into mainstream availability.^[1] It also can be homemade.^[2]

Monaka (最中^?) is a Japanese sweet made of azuki bean jam filling sandwiched between two thin crisp wafers made from mochi. The jam can also be made from azuki beans but also with sesame seed, chestnuts, or rice cake (Mochi).
Modern monaka can also be eaten filled with ice cream.

The wafers can be square, triangular, or may be shaped like cherry blossoms, chrysanthemums and so on.

Monaka is a type of dessert (Wagashi) which is served with tea. There are still many very famous Monaka specialty stores in Japan.
