โญ Vanilla Powder (pure, finely ground) (Best Vegan Option)
1/4 teaspoon per 1 teaspoon vanilla extractPure vanilla powder is made by grinding dried vanilla beans and delivers a concentrated flavor without added liquid, which is beneficial in maintaining Hollandaise's emulsion stability.
To prevent graininess, dissolve the powder in the melted butter phase before whisking with egg yolks. Monitor texture closely to avoid any gritty mouthfeel.
The flavor is slightly less intense than extract but adds a subtle vanilla note without diluting the sauce.
