Ingredient prep checklist
- Katsuobushi: ½–1 cup katsuobushi (dried bonito flakes) ((packed; for a more intense flavor, use the larger amount))
- Mirin: ½ cup mirin ((plus 1 Tbsp, to taste))
Gather all the ingredients. I make the homemade dipping sauce ahead and keep it in the fridge until ready to use—it's a big time-saver. Short on time? Use store-bought mentsuyu from a Japanese or Asian grocery store.
