With just a few ingredients, this butter transforms everyday dishes into gourmet experiences, adding a savory depth that makes flavors pop.
Ingredients
Makes about 1/2 cup (8 servings)
- 1/2 cup (1 stick / 115g) unsalted butter, softened
- 2 tablespoons shio koji (store-bought or homemade)
- 1 teaspoon lemon juice (optional, for brightness)
- 1/4 teaspoon freshly ground black pepper
Preparation Time
- Prep time: 5 minutes
- Chill time: 30 minutes (optional, for firmer texture)

Step-by-Step Instructions

- Mash together with a fork until smooth and fully incorporated.
Step 3: Taste and Adjust
