Lemon Juice (Best Option)
1 tablespoon lemon juice per 1 tablespoon white vinegarLemon juice works well as a substitute because it has a similar pH and acidity level to white vinegar, which helps to balance the richness of the risotto. The citric acid in lemon juice enhances flavor without adding sweetness or color.
When using lemon juice, add it gradually and taste as you go to avoid overwhelming the dish with citrus notes. Freshly squeezed lemon juice is preferred over bottled for the best flavor.
Compared to white vinegar, lemon juice imparts a slightly fruitier acidity but maintains the essential brightness needed to cut through the creaminess, keeping the risotto balanced and flavorful.
