Can lime juice be substituted for key in a recipe?

No, lime juice cannot be used as a substitute for key lime juice in any recipe. While both key limes and limes belong to the citrus family, their flavor profiles and chemical compositions are quite distinct. Key limes are smaller and less acidic than limes, and they have a unique aroma that is often described as floral or musky. Lime juice, on the other hand, is more sour and does not possess the same flavor characteristics as key lime juice. Substituting key lime juice with lime juice in a recipe can significantly alter the taste and overall flavor balance of the dish.
