⭐ Lemon Juice (Best Dairy-Free Option)
1 teaspoon per 1 tablespoon apple cider vinegarLemon juice is a natural acidic agent with a pH similar to apple cider vinegar, which helps to stabilize the emulsion of egg yolks and butter in Hollandaise sauce. Its citric acid content provides the tang necessary to cut through the richness without overpowering the flavor.
When substituting, use slightly less lemon juice than the amount of apple cider vinegar called for, as lemon juice can be more potent. Freshly squeezed lemon juice is preferred for the best flavor and acidity control. Avoid bottled lemon juice with additives that may affect taste.
The final sauce will have a slightly more citrus-forward profile but remain balanced, bright, and creamy, preserving the classic Hollandaise characteristics.
