Citric acid, also known as “sour salt,” is a common ingredient in the culinary world, and is often used in cooking and baking to add a tart, sour flavor. It’s also a key component in some food preservation methods due to its high acidity.
However, there may be times when you need a substitute for citric acid, whether it’s due to dietary restrictions, taste preferences, or simply because you’ve run out.
Two of the best alternatives are lemon juice and vinegar, both of which can deliver the tangy kick that citric acid offers.
👅 Flavor Profile
Citric acid has a tart, sour taste, akin to that of citrus fruits like lemons and limes, though it’s a bit more concentrated. It’s used in small quantities to enhance flavors, balance sweetness, and even act as a preservative.
The texture isn’t usually considered as it typically dissolves into the rest of the ingredients, leaving no significant residue or texture.
🔄 The Closest Replacements/Substitutes
