Imagawayaki (今川焼き) is a Japanesedessert often found at Japanese festivals as well as outside Japan. It is made of batter in a special pan (similar to a waffle iron but without the honeycomb pattern), and filled with sweet azuki bean paste, although it is becoming increasingly popular to use a wider variety of fillings such as vanilla custard, different fruit custards and preserves, curry, different meat and vegetable fillings, potato and mayonnaise.[1][2] Imagawayaki are similar to Dorayaki, but the latter are two separate pancakes sandwiched around the filling after cooking, and are often served cold.
