Shio Koji in short means “ Salt Koji.” You take koji, salt, and water and let it sit for around 10 days. What I find most interesting about the Shio Koji process is that salt actually kills the Aspergillus oryzae. Lucky for us, it’s enzymes remain and when you throw into the mix the carbohydrates and sugars that exist in grains and by creating the right fermentation environment you are able to grow some solid bacteria. What does this mean for us? We have this amazingly tasty, umami, bacterial goodness that we can use to create other fermentations or secondary fermentations.
Here’s a list of some of our favorite uses for Shio Koji:
Shio Koji cured meat
Shio koji in handmade pasta (a lovely trick we learned from Ourcookquest)
Sauces & Marinades
An alternative for soy sauce
Alternative ways to make pickles
Here’s our recipe for Shio Koji :
2 cups koji
2 cups water
1/8 cup salt
Mix together well and move to a jar with a finger tight lid. Let it sit in a cool and dark place for 10-12 days. Every day you’ll want to stir or shake the mixture. When it’s complete you can opt to blend the mixture or leave it in it’s original state and then move it to the fridge. Shio Koji can be used for 6 month from the date of making — so make sure you date it.
Hoshigaki are a Japanese delicacy made by gently massaging persimmons while they air dry. The persimmons used to make Hoshigaki are astringent varieties such as Hachiya. Ideally, choose fruit that still has part of the stem. We've used a couple different varieties of persimmons with nice success.
1) The first step is to cut the top off, while carefully leaving the stem that you will tie string to and they will hang from. And then use a knife of peeler to trim away the skins of the persimmon. Then attach the string and find a good place for your Hosigaki to hang. Broom handles work great for this, we've also used knitting needles, drumsticks and hangers to hang the Hoshigaki from.
2) The first week you just let the Hoshigaki hang and dry till they start to create a thin skin. After a week has passed you begin to gently massage each persimmon every other day. Be careful not to break the skin.
3) As you keep massaging every other day the fructose in the fruit will begin to come to the surface. The "bloom" begins to appear...it looks like powdered sugar on your persimmons. Keep massaging until the persimmons are more like a dried fruit, changing into a darker color with the bloom, and then enjoy!
