Foreign Foods in Japan –

So many of our Foreign Foods in Japan have come from Europe, the US and China, so this month we’re finally focusing on Japan’s neighbor to the north…Russia!

Piroshiki are hand-held dough pockets filled with various types of fillings. The original dish from Russia is spelled as pirozhki, piroshki or when plural, pirogi or pierogi. In Russia, pirozhki can be found all over the place, made at home, in restaurants and at street food stalls. The Russian version is commonly filled with meat, vegetables, cheese and infrequently fish, when savory, or with fruit and jam when sweet. The dough is typically a yeast dough, leavened and brushed with egg wash, and the entire pocket is baked in a hot oven…perfect for the cold Russian climate!


In Japan, pirozhki were adapted to Japanese taste and cooking methods. One account states that this dish was introduced to Japan after WWII, and the original Japanese piroshiki were filled with minced onions, boiled eggs and ground beef and deep-fried, instead of baked. Another states that Miyo Nagaya, a Japanese chef from Tokyo, became interested in the cuisine of Russia and Central Asia, and opened a restaurant in Tokyo in 1951, where she modified the Russian dish to Japanese tastes.


Today, piroshiki can be found at bakeries and restaurants in Japan and frying is still the most common way of preparing the dish. Typical fillings range from ground meat, fish and vegetables such as onions, carrots and shiitake mushrooms. One delicious and unique Japanese-centric filling is cooked and chopped up harusame glass noodles, which add incredible texture and umami to the piroshiki. Some believe that piroshiki were the inspiration for kare-pan or curry pan, which is a beloved Japanese deep-fried dough pocket filled with curry flavored ingredients.


No matter where you get your piroshiki in Japan, you’re sure to enjoy this hot pocket. Have you had it? Have you made it? Share your favorite recipe with us below!

Foreign Foods in Japan –

Dorias are so quintessentially Japanese that we sometimes forget they were once a foreign food introduced into Japanese cuisine!

Many foreign foods were introduced to Japan during the Meiji Era, from 1868-1912, as Japan began its journey towards global modernization. After the First World War, even more foreign influence permeated the country, and foreign-born and trained chefs began introducing new dishes inspired by their homelands yet catering to Japanese tastes. One such dish is the doria. It is said that Saly Weil, a Swiss master chef at the New Grand Hotel in Yokohama, developed the dish in the 1930s. The dish was inspired by classic French gratins and baked Italian casseroles, with signature components including a creamy béchamel sauce and melted cheese.

Instead of being made with potatoes, similar to pommes de terre gratinees, the Japanese doria was made with the local staple: rice. And while European gratins often featured beef or ham, the Japanese version most commonly used seafood. Today, numerous variations exist among Japanese dorias, including ones with vegetables, chicken, mushrooms and a host of other ingredients!

The classic Japanese doria starts with cooked white rice. The rice is typically buttered, and depending on taste seasoned with aromatics such as garlic or herbs such as parsley. To the buttered rice is added seafood such as shrimp, scallops or fish, or chicken or vegetables, such as broccoli and mushrooms. And the entire mixture is then folded into a classic French béchamel sauce, made of butter, flour and milk. The combined ingredients are layered into a baking dish and topped with meltable, creamy cheese, such as parmesan or gruyere. The dish is then baked until the cheese is golden on top.

Dorias are served at Yoshoku restaurants throughout Japan but are also frequently prepared at home for lunch or dinner. Our classic recipe is the Green Peas and Asparagus Doria, which is made using rice cooked in our rice cookers.

Have you made this comforting dish? Try it out…it’ll be great for the coming winter months!

Foreign Foods in Japan –


It’s delicious. It’s uniquely Japanese. And it’s not a hamburger!


Our Foreign Food this month is a delicious Japanized version of steak, with similarities to Salisbury Steak, Steak Tartare and the Hamburg steak from Germany. Hanbāgu is a ground meat patty made from beef and pork, served like a steak, topped with a sauce and typically accompanied by rice and vegetables. This type of chopped meat steak became popular in the United States in the late 1800s, when German immigrants from Hamburg came to live in American cities like Chicago and New York. They made a “steak” with chopped beef mixed with onions, garlic, salt and pepper and cooked until tender and juicy.

Eventually, these steak patties were adapted to be eaten between two pieces of bread, creating the modern American hamburger, and both the chopped beef steak and hamburger were brought to Japan during World War II with the influx of foreign soldiers into the country.

Hanbāgu patties

Hanbāgā evolved to become Japanese hamburgers – beef patties served with various toppings served in a bun. Hanbāgu evolved as a rich and savory steak dish, cooked by countless Japanese home cooks, becoming a favorite dish among children and adults.

Hanbāgu is made with a blend of beef and pork called aibiki. This mixture is commonly mixed at a ratio of 7:3 and is typically found prepackaged at Japanese stores. Into the meat are added sautéed onions, egg, panko breadcrumbs, milk, salt, pepper and nutmeg. The mixture is mixed by hand into a gruel-like consistency and formed into patties. The Japanese technique of forming the patties adds a special touch to the meat. The patties are tossed back and forth in the hands, removing air pockets and then indented on the middle to foster even cooking. The patties are also rested in the refrigerator prior to cooking, allowing the slow absorption of flavor from the seasonings.

Pan frying some Hanbāgu!

Once the patties are ready to cook, they are pan fried, instead of grilled, similar to a steak. Red wine or another liquid can be added to the par-cooked patties, and they’re finished covered, having absorbed the liquid for extra flavor.

Traditionally, hanbāgu is served topped with a demi-glace sauce, but a red wine reduction or other savory sauce is also commonly served along with rice and vegetable accompaniments.

Mini Hanbāgu are perfect for bento!

Hanbāgu is such a cultural staple and easy to make using our electric skillets. Try our Mini Hamburger recipe for your bentos, and share your favorite way of enjoying hanbāgu!
