Tuna tataki
============ 2015-xx-xx


Comment: Ideally the piece of tuna should have a regular shape and be thick enough (4 to 6 cm). It will be necessary to marinate the tuna for ~12 hours, so plan accordingly.

for 1 serving

Ingredients:
------------

1 nice piece of red tuna of regular shape (150 to 200 g)
soja sauce
rice vinegar
mirin
sake
sesame seed oil
ginger
sesame seeds (opt)
prepared ponzu sauce  


Preparation:
------------

Prepare a bowl of icy water (water with a few ice cubes).
Prepare a large enough piece of kitchen film (saran wrap).

Sear the tuna piece on all sides in a very hot pan with a little bit of high temperature oil (grape seed oil).
Sear on all faces for 15 s (20 s max) using tongs (be careful not to damage the tuna by squeezing too hard).

Wrap the tuna in the film and dip it in the ice water to cool quickly (to stop the cooking).

Prepare a marinade of:

1 part soja sauce
1+ part rice vinegar
2 part sake
0.2 to 0.3 part sesame seed oil
~2 cm grated ginger root.

Pour it in a ziploc bag, with the tuna and let marinate 12+ hours in the fridge, turning it one of twice to spread the marinade evenly.

To serve:
---------

Optionnaly roll the tuna in sesame seeds.
Cut in thin slices against the grain (3 to 4 mm).
Eat dipped in ponzu sauce as for sushi.
