How do I make seasame seeds stick to tuna?

[bw2082]

I want to make a seared, sesame seed encrusted piece of tuna, but every time I've tried this, I can't get the seeds to stick. Is there a trick to this? Some of the seeds do stick and get embedded in the tuna, but most of the time a lot of it falls off, especially if i grasp the piece with tongs to turn it. What I have been doing is just rolling the piece of tuna in seeds and then searing quickly for a few seconds on each side so I can keep it rare inside. Should I try brushing with egg white or something like that to make the seeds adhere better?

You can spread wasabi paste (wasabi powder found in spice section of bulk in grocery mixed with water) and then press into seeds...delicious!

I agree with lunchbox..Hoisin sauce should do the trick, it's nice & thick.

Hmm, I typically well either marinate the tuna in some oil, ginger, rice wine vinegar, soy sauce, etc. and then coat in sesame seeds and sear a minute or so on each side for rare and rest, slice and serve. I never had a problem w/ seeds not sticking. I don't put any oil in the pre-heated pan either. If you don't want to marinate your tuna, trying brushing with a little sesame oil.

I usually rub the tuna with a complimentary Asian sticky sauce- either sweet soy, hoisin, char siu, etc... ina thin layer, then press the seeds on-
Sticks well and tastes great

Lightly roll or crush the seeds to flatten them so they have more surface area.

cool idea, veggo.

not egg white.

rub the tuna with oil if you don't use a marinade.

So you didn't coat the fish with something?

It's been a while since I've done this but the last time I patted the tuna dry, then painted a mix of mirin, soy and sake onto the side being coated and then placed coated-side down into the seeds. I also used a blowtorch to cook the tuna but that's because I didn't want too thick of a cooked layer.
