Sergio Lorenzi sends me these photos of a vending machine he found in Nagoya with flying fishes inside a bottle. The text say that the flying fishes have been grilled and are ideal to use as a soup (dashi) to give flavour to udon, nabe, oden or any other slow cooked recipe.
Each bottle, in addition to a flying fish, also has some konbu 昆布 algae, one of the essential ingredients to be able to obtain the umami flavor when cooking.
