Step 1

Combine all the poaching ingredients in a large pot set over medium-high heat. Bring to a boil.

Step 2

Add the calamari and squid heads and allow to poach for a minute or two until just cooked. Drain with a slotted spoon and add to a large bowl.

Step 3

Add the shrimp and mussels then turn off the heat and allow to poach for 4-5 minutes until just cooked.

Step 4

Drain with a slotted spoon and add to the bowl with the calamari.

Step 5

In a separate bowl, mix together all the dressing ingredients.

Step 6

Taste and adjust seasoning if necessary. I like to make the dressing a little too acidic and too salty to make sure the seafood is well-seasoned.

Step 7

Pour the dressing over the seafood then add the finely chopped celery and red onion.

Step 8

Stir to combine then allow to marinate for 30 minutes then serve.
