I have posted many dishes using octopus which we got from different sources. We like octopus legs (boiled and frozen) from D’artagnan and Great Alaska Seafood. Interestingly, both are “Spanish octopus legs”. The offer we recently purchased from Great Alaska Seafood included quite a large amount of octopus legs so I have the luxury of using it fairly regularly. The last time I used it, after thawing, I reserved about 2 inches of the octopus leg to eat as “sashimi*” 刺身 and I made the remainder into tender simmered octopus タコの柔らか煮 using an Instant pot. We usually eat octopus sashimi with wasabi and soy sauce or sumiso but this time, I tried a different dressing using salted plum or “Umeboshi” 梅干し (I used some umeboshi we received quite a few years ago from my mother the last time she made it. We kept it in a sealed container in the refrigerator. It looked and tasted good). I also served two small appetizer dishes.
*Most common “sashimi” of octopus is previously boiled legs because raw octopus is extremely perishable. Real “raw” octopus can be had in Japan. The first time we had “raw” octopus sashimi was in Kobe 神戸 many years ago. Because of the location of Kobe, very fresh octopus from the Japanese inland sea 瀬戸内海 was available. Now, because of the advancement in the logistics of transporting fresh seafood in Japan, it is more readily available throughout Japan. As a matter of fact, we had raw octopus sashimi at Tako Grill in Kuroishi 黒石, Aomori prefecture 青森県 in Japan.
