Satsuma-age is a fried fishcake originating from south Japan in Kagoshima. There isn’t any magic, it is surimi and flour is mixed to make a compact paste that is solidified through frying.
The paste is made from fish and seasoned with salt, sugar, and other spices and molded into several shapes. It is made not only from ground fish but can include beni shōga, onion, and other vegetables, or in this case they use shrimp paste.
Surumi isn’t typically made in Kyoto and when compared with the industrial type sold in America best known as the fake crab used in sushi rolls – its a different matter all together.
