2 ingredients Simple Shio Koji Beef Steak

Have you heard of Shio Koji? If not, you are lucky for stopping by my blog. If you have, I assume that you are very into Japanese food. Shio Koji is a magical seasoning made from salt, malted rice and water. It not only tenderizes meat and fish, but also brings out the flavor, known as Umami. Shio Koji is my answer to make restaurant-quality steak at home.

What is Shio Koji?

Shio Koji is one of the traditional Japanese ingredients. It was a trend of Shio Koji in Japan a couple years ago, and now became a common household ingredient.
Shio means salt in a literal sense. And Koji is a breeding of Aspergillus oryzae, which is one of the types of mold growing on rice, wheat, soybeans and other grains. But don’t take it creepy, It’s harmless and beneficial to our body the same as other fermentation products such as cheese and yogurt. Japanese condiments such as soy sauce, miso and sake involve the fermentation with its mold.

How Shio Koji works for meat?

In short, Shio koji makes meat tender and delicious.

The reason why meat gets tough is because it contains muscle proteins. It shrinks and hardens when heated it up. Before it become that, an enzyme called protease in Shio koji does a great job, which breaks down the proteins into small pieces.

The great thing about protease is that it also increases amino acid which what we feel about umami in food.

How to use?

It’s very simple. Marinate 10% of Shio Koji of the total weight of the meat, fish or vegetables. 1 tablespoon of Shio Koji is about 20 grams, therefore I used 1 tablespoon of it for 200g of the beef. If you marinate longer times, the meat can be softer. After the marinade, lightly wipe away the excess Shio Koji. You can eat them though, Shio Koji is easy to burnt than not marinated meat. Please pay attention through cooking.

How to store?

Once opened a package, put in a fridge. The package says finish it within few months. However, I think that it would last longer than that. Because my homemade Shio Koji has been kept for about a year with no problem.

You can enjoy amazing steak at the tenderness and flavor!

Do you need to seal the bag during the marination process in the fridge? Thanks for sharing this!

Japan Center probably has Shio koji (塩麹 / 塩こうじ). It may be stored in the fridge close to Tofu or around Miso aisle. Apparently, their online store carries Shio koji. I hope it will help! https://www.japancentre.com/en
