Baking Powder (Best Option)
3 times the amount of baking soda (e.g., 3 tsp baking powder per 1 tsp baking soda)Baking powder contains both an acid and a base, allowing it to react without additional acidic ingredients. In salad dressings, it can neutralize acidity and provide mild effervescence that can lighten texture slightly.
To use baking powder effectively, increase the quantity to compensate for its lower alkalinity compared to baking soda. Monitor for any slight changes in flavor, as baking powder can introduce a subtle tang.
Compared to baking soda, baking powder is less potent and may slightly alter the taste, but it preserves the dressing's overall stability and mouthfeel.
