Shio Koji half day pickled Khol Rabi
|
After reading Koji
Alchemy, I have to admire the work that have been done by those western chefs, extensive
tests on various food items, with detail scientific explanation so that readers
feel safe to follow. Also wondered why I, having eaten fermented rice since
young and in recent years make it and rice wine regularly, have not thought of
such new ways of using it.
Basically koji (the
now well known name for this rice ferment) is a mould that produce enzymes to
convert starch to sugar, protein and fatty acid to smaller chain molecules. The
Chinese version (a dry white ball or cube) contains yeast too, that convert
sugar to alcohol.
Traditionally in Asia,
Koji is used at home on cooked grains, mostly rice, to make the dessert or rice wine.
More experienced people use it to make soy sauce or fermented bean paste.
In this book, the
chefs tested using Koji fermented rice, most often salted with 5% salt (Shio Koji) to pickle
vegetables, converting part of the starch/protein/fatty acid content into more diverse flavors. They
also use it on dairy products, nut, curing meat and fish.... generating new
flavors.

fermented rice with 5% salt
|
I quickly make some
fermented rice, salted at 5% to keep in the fridge, and start playing with it.
First is pickling Khol Rabi for half a day, and cooked potato and egg for a
week.
I have been making half
day salt pickled Khol Rabi every week, love the crunchy mildly sweet taste.
This Shio Koji pickled Khol Rabi is still crunchy and mildly sweet, but with an
underlying floral honey aroma.

Shio Koji cured cooked potato and eggs

The 1 week pickled
cooked egg is nothing special, just feel salty, but the pickled cooked potato
has a celery/parsley herb flavor, very pleasant and most amazing to taste the
result.
