Pepper-Seared Tuna, Limited Illustration Version


Why “Limited Illustration,” you ask?

(I know, I know, you don’t care. Play along.)
 
Due to various technical difficulties, I don’t have any prep or ingredient pictures on this one—just a few pictures of the finished dish. But I posted a picture of it on Facebook, and people seemed to like the look of it, so I decided it would be worthwhile to post it here.

This one is (again) from Nigella Lawson; in this case, I’m pulling a recipe from her book (and eponymous TV series) Forever Summer. Why am I cooking from a summer cookbook in November, you ask? Because shut up, that’s why.

Actually, it has to do with an impulse buy. I am fortunate in that there is an actual, honest-to-gods fish market in the city where I live, and they had some beautiful yellowfin tuna at a (relatively) reasonable price when I looked in last week. So I took home this lovely fresh tuna, but had to figure out what the hell to do with it. I happened upon this recipe, and the rest was history, albeit in very circumscribed and obscure form.

Also, yellowfin tuna is a good/acceptable choice (depending on the variety and fishing method) according to the Monterey Bay Aquarium’s very useful (albeit depressing) Seafood Watch Website. They have a smartphone app as well.

However, I am aware that fresh tuna is not available everywhere (don’t write in). If you can’t get it, you could try another type of fish, but I would actually suggest using a New York strip steak or a boneless ribeye steak instead. The flavor would be different, but similar, and a beef steak can be seasoned and cooked in the same way.

The cooking is fairly simple. You paint the tuna (or steak, or whatever) with a mixture made of 1 tablespoon of dark sesame oil and 1 teaspoon of prepared English mustard. Please note the word “prepared” here. The first time I tried this dish, years ago, I thought Nigella meant dry mustard; she doesn’t, and using powdered mustard will make this kind of pasty and gross. She means this. If you can’t find it, she mentions using wasabi paste as a substitute, but I think Dijon mustard would work as well, possibly mixed with a dab of horseradish—English mustard is hotter than Dijon mustard.

Anyway, you paint the mustard/sesame oil mixture all over the fish, and then you coat the fish with very coarsely cracked black peppercorns. If your pepper mill works well on its coarsest setting, you're good to go. Mine doesn't, so I resorted to putting some peppercorns in a Ziploc bag and bashing them a bit with a frying pan. But if you’re part of the I-only-cook-with-pre-industrial-revolution-methods brigade, a mortar and pestle will work as well.

The next step is to heat a dry pan over high heat. I used my trusty cast-iron skillet for this, but as long as you don't use a non-stick pan, you should be fine. Nigella tells you to then sear the tuna quickly on all sides, so that the outer edges are just cooked, but the inside is still raw/rare. Let it cool a bit (or cool completely, if you like) slice it thinly, and serve.

What Nigella doesn’t mention is that if one’s kitchen has a smoke detector, the smoke created by searing black peppercorns and tuna in a red-hot pan may well set it off, even if one is running one’s exhaust fan. And if one’s smoke detector is not battery-powered but is in fact wired directly into one's home electrical grid, it will be very difficult to deactivate. This can lead to one having to open one’s windows and patio door on a chilly, rainy November evening to give the smoke a way out. And if all of that is going on, it’s not really possible to take pictures of the cooking process. Just sayin’.

But I digress. I’ve served the tuna with some steamed broccoli. This is a long-stemmed type of broccoli which is either marketed as “baby broccoli” or “broccolini” depending on the store and the supplier. It’s nice, but regular broccoli would work fine, as would broccoli raab, or asparagus, or green beans, or whatever other vegetable appeals. I steamed the broccolini until it was just cooked through. I also had some sesame noodles alongside.


La Nige suggests dunking the tuna in soy sauce as you eat. My take on this was to mix about 2 tablespoons soy sauce with about 1 tablespoon rice wine vinegar (cider vinegar will do in a pinch) with a few drops of sesame oil and a little bit of grated fresh ginger. A bit of grated or minced garlic in addition to or instead of the ginger would be nice, too. It didn’t make it into the photos for some reason, but I had a little bowl of this dipping sauce for the tuna and the broccoli.

Anyway, it was good, and it looked pretty. Bon appetìt, y’all.


From Nigella Lawson’s Forever Summer:

Pepper-Seared Tuna

Those of my vintage may remember this dish from the eighties fondly as Tataki of Tuna: a log of ludicrously rubied fish, rolled in pepper, briefly seared and eaten finely sliced with shredded spring onions and twiggy strips of cucumber. Dunk in soy as you eat or make up a few blobs of sinus-clearing wasabi. If you do have some wasabi to hand, you can use this for smearing over the tuna, before coating it with peppercorns, in place of the English mustard stipulated below.

Ingredients:

1 tablespoon Asian sesame oil
1 teaspoon English mustard
¼ cup black peppercorns (crushed roughly)
1 lb sashimi-quality tuna fillet (cut in long even thickness)
cucumber (cut into slender batons)
4 scallions (cut into strips)

Method:

1.     In a small bowl mix the oil and mustard, and use a pastry brush to paint it on the tuna. Roll the tuna in the crushed peppercorns so that the long sides of the log are covered, but the ends are not.
2.     Heat a dry frying pan until it's very hot and cook the tuna on all the long sides, searing the fish to about 3mm / one-eighth of an inch in a circle around the edge. You'll be able to see how much of it's cooked, because the ruby flesh will turn brown and the depth of the ring, if you see what I mean, will be evident from the uncoated round ends. Take out of the pan immediately and cool on a plate.
3.     With a sharp knife cut into the finest slices you can and serve with the cucumber and scallions and soy, dipping sauce, wasabi, as you please.
