What I Look for Before Buying Shio Koji
When I shop for shio koji, I always check the ingredient list first. I prefer products with simple, natural ingredients like rice, koji, salt, and water. If I want the best flavor for marinades or dressings, I look for a fresh, slightly sweet aroma and a smooth texture. I also pay attention to whether it is paste or liquid, since that changes how I use it in cooking.
Where I Usually Buy Shio Koji
I’ve found shio koji in a few reliable places. My first choice is often an Asian grocery store, especially Japanese markets, because they usually carry authentic brands.

I usually compare the price per ounce or gram instead of just looking at the total price. Some brands cost more but offer better quality and stronger flavor, so I weigh value against convenience. I also compare the salt content, because some shio koji products are saltier than others and may affect my recipes differently.
