Preparing live octopus to remove the fishy smell is “not as difficult as you think”
Cleaning octopus is an important step to create attractive dishes. To clean octopus and remove the fishy smell, follow these steps:
Step 1: Wash the octopus
First, wash the octopus thoroughly with clean water. If you buy frozen octopus, defrost it before washing by placing it in the refrigerator for 24 hours.
Separate the tentacles from the octopus body by cutting directly with scissors or placing them on a cutting board and using a knife. Note that the cutting position must be close to the body and proceed to cut off all the tentacles.
Step 2: Remove the organs
Using a small knife or scissors, cut close to the body to separate the tentacles and the head of the octopus.
Continue peeling the octopus skin from head to tail. Next, cut out the ink sac, gently squeeze the body to push all the octopus teeth out. Then use scissors to cut off and wash.
Step 3: Squeeze the octopus with vinegar, ginger or salt and lemon juice
Finally, squeeze the octopus with vinegar, ginger, salt or lemon juice to completely remove the fishy smell and slime.
