What is poke?

Poke is a Native dish to Hawaii.

Traditionally, fishermen would take the raw off-cuts of fish and season it with various Asian/Japanese flavours such as soy, sesame, green onions, seaweed and eat it as a snack.

Octopus (he'e in Hawaiian or tako in Japanese) is also another common seafood ingredient used in poke preparation.

Poke can be marinated or non-marinated.

Ingredients you'll need

For the spicy ahi tuna:

• ahi tuna: you'll need to find "sushi grade" ahi tuna, which is fish that has been previously frozen to kill off any parasites. (Technically, there's no such thing as "sushi grade" -- it's just whatever the shop deems safe to consume "as sashimi.")*
• Maui onion: has a sweeter, milder taste; if you can't find it, you can use red/purple onion instead
• green onion: adds a little punch of sharpness to the marinade
• light soy sauce: adds salty flavour to the tuna
• rice vinegar: adds a little tang and acidity; if you don't have rice vinegar, you can use a splash of apple cider vinegar or white vinegar
• sesame oil: use a toasted sesame oil; adds a little nutty aroma and flavour to the tuna
• Thai chili: also known as bird's eye chili -- finely diced; if you can't tolerate spice, you can omit it
• chili powder: adds a little spice to the tuna; if you can't tolerate spice, you can omit it

For serving:

• sushi rice: is a short-grained sticky rice used for making sushi; but you can use whatever rice you like
• ponzu: is a citrus-soy sauce that you can find in Asian/Japanese grocery stores; if you can't find it, you can use soy sauce with a little squeeze of lime/lemon
• wakame seaweed: is a seaweed salad flavoured with some aromatics that pairs well with poke; I made my own, but you can use a store-bought version if you like

Expert tips:

*It's best to talk to your fishmonger for guidance on which fish is safe to use in this type of application. (Vancouver locals, I used the ahi tuna from Fresh Ideas Start Here -- which is the same one that they use for their own poke bar).

If you're still not completely on board with eating raw fish, you can always sear the surface of the entire ahi tuna before slicing into small cubes, aburi-style.

You can find most of the ingredients for this recipe in an Asian supermarket. 

How to make it

Prepare the ahi tuna:

Carefully rinse the ahi tuna under cold running water.

Place the ahi tuna on a clean cutting board.

Pat the ahi tuna dry with paper towel. Cut into ½" cubes.

Place the cubed ahi tuna into a clean glass bowl.

To the ahi tuna, add in the diced onion, green onion, soy sauce, rice vinegar, sesame oil, and chili and chili powder (if you can't tolerate heat, you can omit the chili/powder).

Gently mix the ahi tuna with the marinade. 

The ahi tuna will soften slightly as it marinates in the soy mixture.

Let it marinate overnight, or a minimum of 6 hours. (The longer the tuna sits in the marinade, the more flavourful it will be).

How to store

Store the marinated ahi tuna in an airtight, non-reactive container in the fridge for up to 2 days.

It's best to keep each component for the poke bowl separately, until ready to serve.

How to serve

Serve the marinated spicy ahi tuna on cooked or crispy sushi rice, with various toppings in a poke bowl, or you can enjoy it on its own as a snack.

Topping ideas & variations 

There are lots of toppings and variations as to what can go into a poke bowl.

Try switching out the ponzu sauce for a spicy mayo sauce.

Add fruit such as pineapple or mango.

Pair the tuna with a different type of carb such as brown rice or quinoa.

Or try zucchini noodles.

You can experiment with using smoked salmon or an aburi-style (torched) salmon if you don't like raw fish.
