Just cut and freeze! How to freeze konnyaku

How to freeze konnyaku

There has been a method of freezing konnyaku for a long time, and it is called frozen konnyaku. Frozen konnyaku is a traditional preserved food made by repeatedly freezing and drying to remove the moisture.

When konnyaku is frozen, the moisture will be removed and it will become like a sponge. Because it becomes spongy, it absorbs the flavor easily and has a delicious meat-like texture.

To make frozen konnyaku, simply cut the konjac into bite-sized pieces, place in a storage container, and freeze for at least 24 hours.
It's easy to use if you change the way you cut it depending on the dish you're using it for.

For example, when using it for fried chicken, sweet and sour pork, or simmered dishes, cut it into bite-sized pieces. As a substitute for thinly sliced meat or bacon, it's best to cut it into thin slices when using it in stir-fries, or cut it into 1.5cm dice when using it as minced meat.

Precautions when freezing

If you are concerned about the unique smell of konnyaku, you can make it easier to eat by preparing it and freezing it. Cut the konnyaku into easy-to-use pieces, rub it lightly with salt, and quickly blanch it in boiling water to remove the scum and odor.
Also, the recommended time to freeze is 24 hours. If frozen for a long time, the texture and flavor will deteriorate, so we recommend freezing the food the day before you want to use it.

How to use frozen konnyaku

When using frozen konnyaku, take it out of the freezer and let it thaw naturally or soak it in hot water.
Once thawed, use kitchen paper to squeeze out the moisture.

If you are going to use it for boiled food, it is okay to remove some water, but if you are going to use it for deep-frying, you should remove the water thoroughly. If there is any water remaining, the oil will splatter, so it will be easier to cook if you drain the water properly.

When defrosting, be careful not to defrost in the microwave.
If you are in a hurry or don't have time, defrosting food in the microwave is convenient as it can be done in a short time.

However, if you thaw frozen konnyaku in the microwave, the water will evaporate and it will become dry.
Therefore, defrosting frozen konnyaku in the microwave is not recommended.

Frozen konnyaku diet

Health benefits of konnyaku

Konnyaku is a low-calorie food with 5kcal per 100g, making it a good food for dieting.
Additionally, konnyaku is rich in calcium and a dietary fiber called glucomannan.

The calcium contained in konnyaku is alkaline, so it is easily absorbed by the body and has the effect of preventing osteoporosis.
Glucomannan has the ability to suppress cholesterol levels, remove harmful substances from the body, and prevent arteriosclerosis.

It also has the effect of eliminating unnecessary sodium from the body, so it is an ingredient that people with high blood pressure should actively consume.

Glucomannan has many benefits for women as well.
Glucomannan is a water-soluble dietary fiber that helps regulate the intestinal environment and relieves constipation.

When your intestines are cleansed and constipation is resolved, pimples and dull skin will disappear, and your skin will become clearer.
Konnyaku also contains a moisturizing ingredient called ceramide, so it can also have beauty effects.

Benefits of frozen konnyaku

Konnyaku is low in calories and good for your health, but freezing it gives you even more benefits.

Freezing the konnyaku makes it more chewy than regular konnyaku, and increases the number of times you can masticate it.
Chewing your food well will prevent you from eating too quickly and will help you feel full with less food than usual.

When frozen, konjac becomes meat-like in texture, so it can be used as a meat substitute.
By using frozen konjac instead of meat, you can significantly reduce calories, and it's also good for your intestines, making it an excellent diet.

Konnyaku is also cheaper than meat, so it saves you money and has economic benefits.
