Caprese salad is a classic I come back to again and again, but this version is my personal favorite. What makes it special? Instead of using plain salt, I season it with shio koji—a Japanese seasoning made from rice koji, salt, and water.

Shio koji brings a subtle sweetness and a gentle boost of umami that really elevates the flavor of the tomatoes and mozzarella. Plus, since shio koji is a fermented food, it’s also a gut-friendly choice.
