⭐ Cream of Tartar and Baking Soda (Best Fat-Free Option)
1/4 teaspoon cream of tartar + 1/8 teaspoon baking soda per 1 teaspoon baking powderCream of tartar is an acid that reacts with baking soda (a base) to produce carbon dioxide gas, mimicking the leavening action of baking powder. In Hollandaise Sauce, this helps maintain the right pH and prevents curdling while preserving the emulsion.
To ensure success, mix the cream of tartar and baking soda thoroughly before adding to the sauce. Avoid adding too much as excess gas can cause bubbles or separation.
Compared to baking powder, this combination offers a fresher, more controlled reaction that supports the sauce’s delicate texture and flavor without introducing unwanted bitterness or graininess.
