Vanilla Extract (Best Option)
1/4 teaspoon per 1/2 teaspoon almond extractVanilla extract shares a similar aromatic profile with almond extract, providing sweet and floral notes that enhance the buttery richness of Hollandaise Sauce. Both extracts are alcohol-based, which helps them disperse evenly in the emulsion.
When substituting, use half the amount of vanilla extract to avoid overwhelming the sauce with sweetness. Stir gently to incorporate and avoid breaking the emulsion.
The final sauce will have a slightly different but complementary flavor, maintaining the smooth texture and enhancing the overall taste without introducing nut allergens.
