In China and Japan on New Year’s Day, long noodles are considered a lucky food because they symbolize long life. This spicy-sweet yakisoba recipe from Iron Chef Masaharu Morimoto is Japanese street food at its best — quick, easy and incredibly flavorful.

It doesn’t take a lot of technique — just keep the ingredients moving — and you don’t even need a wok; a cast-iron pan works just fine. Yakisoba noodles and sauce are readily available at Asian markets, but if you can’t find them, substitute cooked ramen noodles and a homemade sauce of 2 tablespoons each ketchup and mirin, 4 tablespoons each soy and Worchestershire sauces, and a dash of sriracha.

Don’t be afraid to slurp when eating. That will bring even more luck.

Yakisoba

2 Tbsp. vegetable oil

2 oz. pork shoulder, sliced thin

1/2 cup thinly sliced yellow onion

1/4 cup 2-inch-long matchsticks peeled carrot

1 cup roughly chopped (about 2 by 3/4-inch pieces) loosely packed white cabbage

5 1/2 oz. package refrigerated yakisoba noodles (a heaping cup)

2 Tbsp. jarred yakisoba sauce

1 Tbsp. shredded beni shoga (red pickled ginger)

1 heaping Tbsp. bonito flakes

1/2 tsp. aonori (powdered seaweed) or finely chopped nori seaweed sheets

Heat oil in a medium-wide nonstick or cast-iron skillet over high heat until oil shimmers. Add pork, onion and carrot and cook, stirring frequently, until pork is no longer pink, about 2 minutes. Add cabbage and cook, stirring, until it wilts slightly and the onion is lightly browned at the edges, about 3 minutes.

Add noodles and cook, tossing with tongs, until noodles are heated through. As you toss, gently separate the strands; if noodles don’t separate easily, add a splash of water to pan.

Add sauce and continue to cook, tossing, until thoroughly coated, about 1 minute. Season with more sauce to taste, toss well, and transfer to a bowl. Top with the pickled ginger, bonito flakes and aonori. Eat right away.
