We Japanese love to massacre modify different Western cuisines to make them suit our taste. (You might remember the soy sauce-based mushroom spaghetti I wrote about a while back.) One of the frequent victims is the Italian food--there are quite a few spaghetti dishes that you don't see anywhere outside of Japan, or outside of Japanese cooks' kitchens. We might add miso to a simple tomato sauce to give it an extra depth of flavor. "Natto," fermented soybeans, also makes its appearance in spaghetti dishes. We might even use "shiokara," various seafood, often squid, marinated and fermented in its own innards (I know it sounds gross, but a good one can be fantastic) as a base for the sauce.

Though I'm not a huge fan of "natto spa," as this type of spaghetti is often called, I am deeply in love with another perennial Spaghetti Giapponese: spaghetti with spicy pollack roe. Spicy pollack roe, originally from Korea, is raw pollack roe preserved in salt and red chili, and is usually eaten with a bowl of rice or as an accompaniment for sake. Mentaiko, as it's called, can be a little bit daunting for someone with an aversion to oceanic flavor (I had to overcome my initial revulsion, too, since mentaiko smells pretty fishy), but once you get over it, it can be quite addictive. Mentaiko loses some of its wild fishiness when it's cooked, so spaghetti with mentaiko (or "mentai spa" in short) is one of my favorite dishes that involve this ingredient.

I don't know who invented the "mentai spa," but it's a pretty simple dish. In fact, I might venture to say that its simplicity faithfully reflects the simplicity of Italian pasta dishes. The main ingredients are the spaghetti, mentaiko, butter, soy sauce and nori (seaweed you find wrapped around your "maki" sushi). It's simple, but the fishy, salty mentaiko, the fatty, rich butter and the aromatic nori blend extremely well with each other. And it's ridiculously easy to make; it's one of the easiest meals to cook, even if you don't know how to cook at all. Indeed, there's no knife involved, either, other than the butter knife you might use to transfer the butter from the butter case to the pan.

Spaghetti with Spicy Pollack Roe (for one)

• 3-4 oz spaghetti
• 2-3 inch spicy pollack roe
• 1 teaspoon butter
• 1/2 tablespoon soy sauce
• 3x3 inch square of nori (or a small handful of pre-crushed or shredded one)
• 2 shiso leaves (a nice touch, but optional)

First, boil the pasta in plenty of water with a pinch of salt. While the pasta is cooking, squeeze the pollack roe out of its thin skin. To get the tiny roe out of the fragile skin, I like to cut one end of the roe sack and pull the sack between two chopsticks tightly held together, but if you aren't used to using chopsticks, you can also do this by breaking the sack open and scrape the roe out with a spoon. When the pasta is al dente, drain the water from the pot, remove it from heat, and add butter, pollack roe and soy sauce. Mix well. The pollack roe cooks by the heat of the pasta. Place the pasta on a plate and top it with shredded nori and shiso leaves, cut into thin strips.

The other day I made this spaghetti for lunch, for the first time in many, many years, and totally fell in love with it again. The punchy heat and fishiness of the mentaiko had morphed into incredibly delicate hint of spice and oceanic flavor, and the butter's dairy richness held it all together. (Just writing this makes my mouth water... Ah!) For folks out there with higher seafood tolerance, I highly recommend this Japanified Italian recipe. Oh, yeah, you should eat it with a pair of chopsticks, too!

---------------
Mentaiko can be found in freezer cases in Japanese or Korean markets. They may come in fancy packages, since they're a bit more expensive. (I think I bought mine, a fake-wood box of 7 oz for $12 or $16.) They're expensive, but you really don't need a ton of them to give flavor to your dishes, so a relatively small package should last you for a while. I got mine at the H Mart (801 Civic Center Drive, Niles, IL).
