⭐ Soy Sauce (Best Fat-Free Option)
1 teaspoon per 1 tablespoon Fish SauceSoy Sauce contains glutamates that provide umami similar to Fish Sauce, enhancing the savory depth of Béarnaise without introducing fishy notes. Its liquid form allows it to integrate smoothly into the emulsified butter and egg yolks.
For best results, use light soy sauce to avoid overpowering saltiness and bitterness. Adjust salt carefully since soy sauce can be saltier than fish sauce. Incorporate gradually and taste frequently.
The final Béarnaise will retain its classic creamy texture and herbal brightness, with a slightly different but pleasant umami profile that complements the tarragon and shallots effectively.
