Cucumber and whitebait in sweetened vinegar

This summer is really hot in Japan. Then I would like to eat a cool food for dinner. The food I introduce today is cucumber and whitebait in sweetened vinegar. It is cooked very easily and simple taste. Moreover, its appearance shows an image of summer. This may be inconsistent with cool. Although Japanese people remember the season of summer to look at or listen to the image of cool.

For example, the other images of cool are tofu, watermelon and wind bell. These images make us to remember the season of summer and the memory of summer.
