Can you use orange juice instead of vinegar in a cake recipe?

No. Orange juice is not a suitable substitute for vinegar in a cake recipe. Vinegar has a unique acidic quality that is essential for activating baking soda, causing the cake to rise. Orange juice, on the other hand, is primarily composed of water and sugar and does not possess the acidity required for this chemical reaction. Replacing vinegar with orange juice could result in a dense, flat cake with a compromised flavor balance.
