If pre-cooked was not available, don't worry, I'll explain how to cook it.
Place the octopus inside the Instant Pot® without water, cook for 18-20 Minutes per 2 lb (1 Kg). Don't worry about not adding water to the pot, the octopus will release its own "juices". Once the time is up, open the pot and try a tentacle. Cook another 5 Minutes if needed.
Once the octopus is cooked, cut it, keeping only the tentacles.
On the Instant Vortex panel, press Air Fry, set the time to 10 Minutes, and the temperature to 395°F (200°C). Press Start.
Once Add Food appears on the display, add the tentacles to the rack and sprinkle with avocado oil, salt, pepper, and garlic powder. Close tray and let cook.
When Turn Food appears on the display, turn the tentacles over.
Meanwhile, in a blender add all the ingredients of the aguachile. Blend until a smooth and homogeneous texture is obtained. Taste and adjust the flavor to taste. (Chill for a few minutes).
Remove the octopus tentacles from the air fryer and place them on a plate.
Pour the aguachile over them, and let marinate for a few minutes before serving.
May be served as I did, or fillet and serve sashimi-style.
Garnish Persian cucumber, red onion feathers, coriander leaves and a few drops of olive or avocado oil.
