Design Explained –
Our Half-Circle

Have you seen our half-circle?

It’s subtle. It’s small. It’s white. And it’s an ingenious feature that indicates whether the removable control plugs for our electric grills and griddles are inserted into the appliance properly.

While our rice cookers, water boilers and other electric products are controlled by onboard LCD panels and powered using power cords, our Gourmet Sizzler® electric griddles and indoor electric grills use a removable control plug that serves both functions: to provide power to the appliance and to manage the temperature setting. These high-powered control plugs conduct electricity efficiently to the appliances, allowing them to heat quickly at the temperature set using the control knob.

The control plugs are installed into the sides of the grills and griddles and “click” into place. On the release buttons located at the sides of the control plugs are white half-circles. And while they look cool, they actually serve as a safety feature. When the control plug is installed correctly into the appliance, the entire white area of the half-circle becomes visible. If it hasn’t clicked correctly into place, the half-circle is obscured.

Such a small smart design feature makes a big difference in safety. Zojirushi’s indoor grills and electric griddles are designed so they do not turn on unless all components are installed correctly. The drip tray not set properly? The control plug won’t go in. The control plug not inserted correctly or loose? Power won’t turn on. This way, no one gets burned or hurt by a heated, but improperly setup appliance.

Foreign Foods in Japan –
Hanbāgu!

“Haan-baa-ghu”.

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

Hanbāgu!

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!

Mr. Bento® Stainless Lunch Jar!

Back to school, back to college, back to autumn routines with work and family and friends!

September is here and we’re excited to make creative meals that we can take to school and work in our Mr. Bento® Stainless Lunch Jar (SL-JBE14). Our Mr. Bento® as a lunch jar, is full of convenient features that allow you to customize your to-go meal experience.

SL-JBE with Carry Bag

This lunch jar has five main components: an Outer Container and four Inner Bowls. The Outer Container provides insulation for 2 of the Inner Bowls and is made using our superior vacuum insulation technology. As with our other stainless products, the vacuum insulation keeps the food inside the Inner Bowls hot or cold for hours.

The four Inner Bowls consist of a Soup Bowl that holds up to 9 oz., a Main Bowl that holds up to 15 oz., a Small Side Bowl that holds up to 7 oz. and a Large Side Bowl that holds up to 10 oz. In total, the bowls can hold up to 41 oz. of food!

The bowls are meant to be stacked in a particular order inside the Outer Container. The Soup Bowl rests at the bottom of the Outer Container. The Main Bowl sits on top of the Soup Bowl and comes with an insulated lid that prevents heat from transferring through, keeping the content of the two bottom bowls at ideal temperature. The two Side bowls sit on top of the Main Bowl, keeping food at room temperature.

Each bowl is microwaveable making it convenient to fill them ahead of time and reheat the food before putting them in the Outer Container. All areas that come into contact with foods are BPA-free.

Once all of the bowls have been placed correctly, the outer lid clips easily into place and keeps all bowls intact.

This lunch jar’s large capacity and multiple Inner Bowls allow you to pack inspired meals! A traditional Japanese ichiju sansai meal, which means “one soup, three dishes” fits perfectly into the Inner Bowls. Western dishes, such as soup, Pasta A’la Zo, salad and dessert also work great, and since September is National Bento Month, kyraben or character bento are ideal!

The Mr. Bento® comes in 4 stunning colors – Plum, Blueberry, Carbon Black and Stainless Steel –and comes with a Forked Spoon and a Carry Bag.

In 4 colors – Plum, Blueberry, Carbon Black and Stainless Steel

Add the Mr. Bento® Stainless Lunch Jar (SL-JBE14) to your lunch box collection and enjoy hot, fresh meals all season long. And be sure to share how you fill your lunch jar…we love the creative ideas you all have!

Our Original Vacuum Glass Liners

Last year, we celebrated our centennial anniversary as a company, and with you as our customers, we’ve come so far. Founded in 1918 in Osaka, Japan, our company was founded as the Ichikawa Brothers Trading Company, producing vacuum insulated glass liners for carafes. These glass liners were state-of-the-art in 1918, and remain a proven, innovative technology along with our more modern rice cookers, small appliances and vacuum insulated stainless steel products.

Blowing glass by hand

Glass is a surprising material. We encounter it every day in our drinking vessels, windows, jewelry, art and so on. It seems so commonplace but it’s actually a marvel of science and engineering. In its basic form, glass is made by combining silica – one of the most abundant materials on Earth – with other elements in order to produce a material with unique thermal, optical, chemical, mechanical and electrical properties.

Our vacuum glass liners in the Air Pot® dispensers and carafes are made using medical-grade borosilicate glass. Borosilicate glass is made by adding boric oxide, a form of the element boron. Because of it’s unique chemical composition, borosilicate glass is more resistant to thermal shock than regular soda-lime glass, meaning that it won’t shatter or crack when exposed to sudden temperature change. It’s also clear, moldable and easily cleanable, making it an ideal material for glass liners.

Carafe with a glass liner

To make these glass liners, we first create an outer vessel in the shape and size of the carafe or dispenser, then make an inner vessel, which is placed inside the outer vessel. We then coat the interior of the vacuum wall between the two vessels with silver plating to give it heat reflecting properties. Finally the air between the two vessels is removed to create vacuum insulation, which maintains the temperature of the contents of the inner vessel.

Vacuum Glass Liner

Words don’t do the process justice, so check out our video of how our glass liners are made in our factory in Osaka, Japan.

It’s no wonder that we’ve been obsessed with glass liners for a hundred years. We are proud to manufacture quality products for our customers, using this innovative and wonderful material.

Share your favorite Zojirushi product with us, and let us know if you have one of vacuum insulated glass liner products!

Foreign Foods in Japan –
Omuraisu!

Chicken rice. Omelet. Ketchup.

Our Foreign Foods in Japan series keeps getting better and better!

Omuraisu!

This month we’re featuring omuraisu, or Japanese omelet rice. It’s not found on most menus in the United States, but it’s hugely popular among those who love Japanese food. Omuraisu is a combination of rice, cooked with chicken, vegetables or ketchup, covered by a thin omelet and topped with a savory ketchup. The rice often contains chicken, but can be made vegetarian with items like onions, corn, carrots and peas, and is seasoned with garlic, soy sauce, tomato ketchup and salt and pepper. Home cooks often prefer leftover rice for this dish, so it’s a great way to make an entire meal from a few components.

Chicken rice

The omelet used when making omuraisu is usually thinner and softer than a traditional French or American omelet. Beaten eggs are quickly shirred in oil heated in a skillet and folded over, thin and soft. The cooked rice is plated and the omelet laid on top, both covered with thin drizzles of savory ketchup, usually a mix of ketchup and Worcestershire sauce.

Omelet

There’s nothing more comforting, unless it’s the delicious variations on omuraisu! Omuhayashi, or omuraisu made with hayashi sauce is deeply satisfying. The base of the dish is the cooked and seasoned rice, the soft, draped omelet and then a cooked sauce made with beef, mushrooms, butter, wine and lots of savory seasonings. The hayashi sauce is poured around the omelet, surrounding it like a moat. Every bite is delicious!

Hayashi raisu

Omusoba marries the best of yakisoba and the soft, tender omelet. Yakisoba is prepared as usual, with noodles and vegetables cooked, then stir-fried in a soy-based sauce. Then, the noodle mixture is topped with the omu-style omelet and drizzled with okonomiyaki sauce and creamy Japanese mayonnaise. (Mouth watering, yet?)

Yakisoba

We have a great recipe for omuraisu on our website. Our special version adds mushrooms to the chicken rice along with other delicious ingredients, and uses rice made in our rice cookers. Check it out and tell us how you like it. Wasn’t it the most delicious thing ever?
