HOW TO MAKE ★FROZEN BENTO★ New Normal Bento Prep!(EP220)

Today I want to share with you how to make Frozen Bento.

It’s still hot in Japan, and we should be very careful with Bento.

Where I got the idea is from・・・・

The other day, I talked to a guy from Food Additive company on my job, and he said there is an increasing demand for additives for frozen food that can be eaten naturally defrosted.

If some of the dishes are frozen and packed with rice or other side dishes, it can extend the time to eat safely.

For the current situation of the pandemic, lots of restaurants stated making take out Bentos. 

They are afraid of food poisoning because they don’t know when their customer actually eats the Bento. So they asked them for an additives or something has the same effect.

But actually, there is no such things but a sweetener can do, he said.

This is the sweetener called “Trehalose”

Trehalose used to handled as a sweetener, but now it is listed on food additive.

I’ve got a hint from the conversation, and I did an experiment as usual, and I made it!

You can cut the preparation time in the busy morning!

If want to cut the preparation time in the morning, I think this is a good recipe for you.

All you have to do is pack these frozen karaage or beef Tsukudani into your bento box with some vegetables and rice.

I put Tamagoyaki, cooked red bell pepper and broccoli from my meal prep and sausages in the bento box for my son.

It took me only 15 mins from start to finish.

How does that sound?

I hope you will give this recipe a try!
