Almond Extract (Best Option)
1/2 teaspoon per 1 teaspoon of vanilla extractAlmond extract contains benzaldehyde, which provides a sweet, nutty aroma similar in intensity to vanilla but with a distinct character that enhances focaccia's subtle sweetness. It works well because it does not introduce moisture or alter dough hydration.
When substituting, reduce the quantity to avoid overpowering the bread’s flavor. Mix thoroughly to ensure even distribution in the dough.
The final focaccia will have a slightly different but pleasant aroma, maintaining the bread’s delicate balance without compromising texture or rise.
