Crystalline acid powder. Adds pure sourness without liquid. Used in canning, candy, and bath bombs.
Substitutes
White Vinegar — 1 tbsp white vinegar per 1/4 tsp citric acid. White vinegar provides clean acidity for canning and cheese-making. Different flavor profile.
Lemon Juice — 1 tbsp lemon juice per 1/4 tsp citric acid. Natural source of citric acid. Adds some liquid and subtle lemon flavor. Adjust liquid in recipe.
Lime Juice — 2 tbsp lime juice per 1/4 tsp citric acid. Lime juice adds citrus flavor alongside its acidity, unlike citric acid's pure sourness. The additional liquid volume may affect recipe consistency. Works well in beverages, desserts, and dressings where lime's aromatic terpenes complement the dish rather than distract.
