Troubleshooting Common Issues
Substitute doesn't taste like tuna at all
Increase ocean seasonings: kelp powder, dulse, and lemon juice. Add a pinch of nutritional yeast for umami depth.
Texture is too mushy or paste-like
Mash ingredients less thoroughly, leaving more chunks. Drain excess liquid and add crispy elements like diced celery.
Mixture falls apart in sandwiches
Add more binding agent (mayo, tahini, or mashed avocado). Let mixture chill to firm up before serving.
Flavor is too bland or one-dimensional
Layer flavors: start with salt, add acid (lemon), then umami (nutritional yeast), and finish with herbs (dill or parsley).
