Best Musubi Maker Molds



Hawaiian spam musubi pieces
Spam musubi is huge in Hawaii. Easily make this at home with one of our musubi makers!

People used to think that making musubi and sushi in their homes was an impossibly complicated task. Who can blame them, after seeing sushi being made with a rolling mat by professionals?

Oh, by the way: for the uninitiated, musubi is a snack or lunch food made of a block of rice and wrapped in nori sheet, a black seaweed paper. Ingredients like salmon, tuna, and pickled plum are usually placed on top of, or inserted into, the rice.

Musubi, like sushi, used to be made by using a rolling mat or an improvised mold.

A musubi maker does away with the rolling mat and, therefore, the complex process that assembling sushi used to prove to be.

In a hurry? Here’s our favorite musubi maker from Amazon.

Is Musubi Japanese or Hawaiian?

Musubi is the same thing as onigiri, a Japanese food invention. In Japan, the preferred term varies depending on the region or even household in which it is being eaten. Musubi (omosubi) has a long history in Japan that dates back to the 11th century.

Musubi is believed to have originated from Japan due to the nature of the Japanese rice, which is slightly sticky, used in making it.

It is compacted rice that is molded by hand into a triangle, square, or other shape.

The popular Spam musubi from Hawaii uses a slice of the meat on top of a block of steamed rice.

The literal meaning of onigiri in Japanese means “to hold or grasp something”. That is what musubi, an onigiri adaptation, is. It is the ultimate convenient, tasty, and eat-anywhere snack.

History of Spam Musubi in Hawaii

Following the Japanese attack on Pearl Harbor on December 7, 1941, the United States imprisoned more than 120,000 people of Japanese descent who were living on the mainland. They were put in internment camps scattered all over various states.

Many Japanese citizens had no choice but to flee the mainland to avoid being caught. Some of them found their way to Hawaii. The island already had a significant ethnic Japanese population by then. The first group of Japanese originally arrived in Hawaii in 1885 as laborers in its pineapple and sugar cane plantations.

Also at that point, the US had a strong military presence in Asia and the Pacific that was based in Hawaii.

The new food Spam became a regular part of G.I. rations at the military base, and the convenient meat product eventually was made available to the locals as well.

Due to a strong Japanese influence in Hawaii’s cuisine, the locals were able to craft a dish in which Spam was topped upon the traditional Japanese snack called onigiri.

The simple dish that the locals created is the forerunner of what we know now as Spam musubi. Today, it is sold everywhere on the island, from convenience stores to fine dining restaurants.

How to Make Spam Musubi


  • Steamed white rice, cooked from 3 cups of short-grain rice in 3 cups of water
  • 1 can Spam (12 ounces), cut crosswise into 10 slices
  • 1 tbsp cooking oil
  • Nori, each sheet cut lengthwise into two
  • ¼ cup Teriyaki sauce (optional)

You will also need a musubi maker or mold. Once you have this, it will be very easy to assemble the musubi.


  1. Heat oil over medium heat in a pan.
  2. Put Spam slices in the pan in a single layer and fry for 2 minutes on each side, or until slightly crisp
  3. If you want your Spam just plain and without the teriyaki sauce, proceed to step 5.
  4. Add the teriyaki sauce and continue cooking the Spam until the sauce is fully absorbed. Remember to turn Spam slices once or twice.
  5. Remove from pan.
  6. On a flat surface, line up a nori sheet shiny side down.
  7. Place a slice of cooked Spam in the center of the nori.
  8. Spoon about 2/3 cup of steamed rice into the musubi mold. Press down the rice to pack tightly into a 1-inch thickness.
  9. Lift the musubi mold to release the rice block formed.
  10. Pull one end of the nori and tuck it between the Spam and rice. Pull the other end over and wrap it around the Spam and rice. Moisten this end of the nori with water to seal it tight.

What are Some Other Varieties of Musubi?

You can use just about anything to top the rice in musubi, and then wrap it with nori.

The more popular ingredients that can be used aside from Spam include fish, chicken, scrambled egg, hot dogs, and tuna salad.

There are limitless possibilities: you just need to use your imagination. I have seen musubi with braised beef and ginger being served in some fusion restaurants. There is also such a thing as vegan musubi that has black hijiki seaweed, tofu, and shiitake mushrooms for the ingredients.

If you want to go minimalist, you can do so by having your musubi go without any topping. Simply sprinkle the rice with furikake or umeboshi sour pickled plum.

Musubi can be molded into triangles, squares, balls, or barrel shapes. There are even those that are shaped like stars or even hearts.

Wrap Up

There you have it: our list of the best musubi makers to buy, with reviews.

In the past, some people used to just make use of the Spam can as their musubi mold. However, that doesn’t make perfect musubi, and with the sharp edges of the Spam can, it’s not exactly the safest thing to do.

If you want to try forming musubi using the Spam can, then firstly, you need to clean and dry the can. Then, cut off the bottom part of the can. Some users tape the sharp edges to prevent injury. Use the can itself to press the rice, Spam, and any other ingredients.

It’s difficult to get the finished product out whole, though, and the whole process is just too complicated.

Just eliminate all the guesswork by using a musubi maker!

It doesn’t cost much to get one. Best of all, you will be getting fresh and professionally-made looking musubi in no time at all.

Frequently Asked Questions

What is a musubi maker?

A musubi maker is a press used to compress rice when assembling musubi to form a rice block. It comes in two parts: the shaper and the compressor.

The shaper is the box-shaped piece which you fill with rice. The compressor is the flat piece that usually has a knob on top. It is used to press down the rice to make it more compact and even.

Do you need to refrigerate Spam musubi?

Musubi is best eaten fresh, but if for some reason it cannot be consumed immediately, you should wrap it in a plastic wrap. If it needs to be stored longer, it is best to keep it in the refrigerator.

Rice and nori do not do well when refrigerated. Microwaving them properly will bring rice back to life, but there’s not very much hope for the nori. It will turn soggy, whether you microwave it or not.

I suggest that you just wrap the rice and Spam in the plastic wrap without the nori before putting it in the refrigerator. When it is time for you to eat it, microwave it for maybe around 30 seconds. Then put the nori on it again.
