Pro Tips

• Don’t oversoak the seaweed. Check it after 8-10 minutes; it should be tender but still have a slight bite. Oversoaking can make it slimy.
• For a spicier kick, add a pinch of red pepper flakes or a few drops of chili oil to the dressing.
• Add extra crunch and freshness with thinly sliced cucumber, shredded carrots, or shelled edamame.
• To enhance the flavor, make the dressing an hour ahead of time to allow the ginger and other to meld together.

FAQ

Q: Is all seaweed salad vegetarian
A: No, many traditional and restaurant-style seaweed salads are not vegetarian because the dressing is often made with bonito flakes (dried fish) for umami flavor. This recipe is specifically designed to be 100% plant-based, using ingredients like soy sauce and ginger to create that savory taste.

Q: How can I add more protein to this salad
A: To make this a more filling, protein-rich meal, toss in about a cup of shelled edamame. You could also add cubed firm or baked tofu for another excellent plant-based protein source that complements the flavors well.

Q: What is a vegetarian substitute for bonito flakes
A: This recipe creates a delicious umami flavor without fish by using a combination of soy sauce, dark sesame oil, and fresh ginger. For other recipes, dried shiitake mushrooms or a pinch of nutritional yeast can also be used to add a savory, fish-free depth of flavor.

Q: Can I make this recipe gluten-free
A: Yes, this recipe is easily adapted to be gluten-free. Simply replace the standard soy sauce with an equal amount of tamari or a certified gluten-free soy sauce. Be sure to also verify that your Amazu Sauce is gluten-free, as brands can vary.
