The Secrets of Fermentation
Episode 5
Why does it taste so good?
Is some new taste being added?

MugiDo you add umami to miso?
Hakkoh-chanYou don’t. It’s already inside the soybeans.
MugiBut soybeans don’t taste like miso.
Hakkoh-chanThe taste is too big to reach your tongue.

MugiWhat do you mean, the taste is big?
Hakkoh-chanSoybean protein is joined up in long chains.
Hakkoh-chanLike that, you can’t taste the umami.
MugiSo the enzyme scissors cut it?
Hakkoh-chanYes. Once it’s small, your tongue can tell.
MugiDoes only umami come out?
Hakkoh-chanSweetness and bitterness come out too.
Hakkoh-chanThe starch in rice turns into sweet sugar.
MugiSo no new taste is added.
Hakkoh-chanA taste that was hidden becomes visible.

MugiThe good taste was inside all along.
Hakkoh-chanJoined up big, it just couldn’t be seen.
MugiCut it, and it’s small enough to reach the tongue.
Hakkoh-chanThat’s it. That’s why the flavor opens.
